Ethernet Controller 10/100 Base-T/TX Bus Interface 80-TQFP-EP (12x12) The LAN9254-I/JRX is an EtherCAT SubDevice (slave) controller developed by Microchip Technology, designed to serve as the communication backbone for industrial automation devices participating in an EtherCAT network. The device integrates dual Ethernet physical layer transceivers directly on-chip, eliminating the need for external PHY components and simplifying the design of EtherCAT-enabled equipment such as servo drives, sensors, I/O modules, and other field devices used in real-time industrial control systems. Architecturally, the controller can operate as either a two-port or three-port node, depending on the network topology required. In its standard configuration it functions as a two-port device supporting daisy-chain connections typical of EtherCAT line topologies. When configured as a three-port device, it gains an additional management interface port that can connect to an external PHY or to another LAN9254, enabling star or tree network topologies and allowing the device to act as a branching point within a larger EtherCAT installation. Each integrated Ethernet PHY operates in full-duplex mode and supports automatic crossover detection, so the device can use either straight-through or crossover cabling without requiring manual configuration. Beyond pure protocol handling, the LAN9254 includes a substantial set of general-purpose digital input and output lines, allowing it to be used in simple field devices without requiring a separate microcontroller. For more complex applications, the device communicates with an external host processor through an integrated host bus interface that behaves like simple memory-mapped SRAM, supporting both 8-bit and 16-bit data widths along with multiple byte-ordering conventions, which makes it straightforward to interface with a wide range of microcontroller and microprocessor architectures. Internally, dual process data RAM buffers manage the exchange of real-time process data between the host application and the EtherCAT communication engine, while a dedicated interrupt line notifies the host of relevant internal events. A key feature of the device is its built-in distributed clock mechanism, which provides high-precision timing synchronization across all nodes in an EtherCAT network. This capability is essential for motion control and other applications where multiple devices must act in tight temporal coordination. The controller also provides configurable status indication through standard network activity and link LEDs, along with optional error and run-state indicators that give visibility into the health and operational state of the device at a glance. Power architecture on the LAN9254 is simplified through an integrated linear regulator, allowing the device to be operated from a single primary supply rail while internally generating the lower voltage needed for its core logic. This reduces the external power supply complexity that would otherwise be required to support separate core and I/O voltage domains. The "-I" designation on this particular part number indicates an industrial-grade temperature rating, making it suitable for deployment in factory floor and other demanding industrial environments where extended thermal range and long-term reliability are required. The device is housed in a surface-mount package consistent with dense industrial control board layouts and is compliant with RoHS material restrictions.

Mid-Range Relays, 2 Form C, DPDT, 2 C/O, Coil Suppression Diode, Gold Terminal Plating, 5 A, 28 VDC Coil Voltage, CII FCB-205 Series The M83536/2-024M is a hermetically sealed electromechanical power relay built to comply with the MIL-PRF-83536 military specification family, a standard governing high-reliability relays intended for use in demanding military, aerospace, and defense electronic systems. Devices manufactured under this specification series are designed to meet stringent requirements for mechanical ruggedness, electrical performance consistency, and long-term reliability under the extreme vibration, shock, temperature cycling, and altitude conditions typically encountered in airborne, shipboard, and ground military platforms. This relay is configured as a double-pole, double-throw switching device, meaning it provides two independently switched sets of contacts that can each connect to one of two possible circuit paths, controlled by a single energized coil. This configuration is commonly used in applications requiring simultaneous switching of two separate circuits, such as redundant power path switching, dual-channel signal routing, or coordinated control of multiple subsystems from a single control signal. The relay operates on momentary, non-latching actuation, meaning the contacts return to their de-energized state as soon as coil power is removed, rather than remaining in their last-commanded position. The coil is designed for direct-current control voltage typical of military and aerospace 28-volt electrical systems, a standard power bus voltage used extensively in aircraft, military vehicles, and shipboard electrical systems. The device's flange-style mounting construction allows it to be securely fastened to a chassis or panel, providing the mechanical stability needed to maintain reliable contact performance under the sustained vibration and shock loading common in military platform environments. Internal contact construction uses a silver-cadmium-oxide contact material, chosen for its strong arc-resistance and resistance to contact welding under repeated switching of inductive or resistive loads. As a hermetically sealed device manufactured to a formal military specification, the relay undergoes rigorous qualification and lot-acceptance testing to verify long-term mechanical and electrical performance, including extended life-cycle switching tests, vibration and shock qualification, and environmental exposure testing. This makes the part suitable for use in flight-critical, mission-critical, or other high-reliability electromechanical switching applications where field failure is not an acceptable risk. The relay is supplied with through-hole solder-pin terminations for both coil and contact connections, supporting traditional through-hole assembly methods consistent with the conservative, well-proven manufacturing processes favored in military and aerospace hardware production.

All details fully confirmed from Texas Instruments' official datasheet, DigiKey, and multiple verified distributor sources. Here's the complete spec. Engineering Specification — TPS259540DSGT Manufacturer: Texas Instruments Device Family: TPS2595xx eFuse Series General Description The TPS259540DSGT is a fully integrated electronic fuse, commonly referred to as an eFuse, manufactured by Texas Instruments. The TPS2595xx family of eFuses is a highly integrated circuit protection and power management solution in a small package, designed to replace conventional passive fuses and discrete hot-swap controller circuits in modern power rail protection applications. Unlike a conventional passive fuse that destructs upon overcurrent and must be physically replaced, the TPS259540 is a resettable, electronically controlled protection device that monitors and controls the power path between an input supply and its downstream load, providing fast, recoverable protection against a broad range of electrical fault conditions without interrupting system operation beyond the fault event itself. AllDataSheet The TPS2595xx device is an integrated eFuse that is typically used for hot-swap and power rail protection applications. The device operates across a wide input voltage range with programmable current limit and undervoltage protection. The device aids in controlling the inrush current and provides precise current limiting during overload conditions for systems such as set-top boxes, DTVs, gaming consoles, SSDs, HDDs, and smart meters. The device also provides robust protection for multiple faults on the sub-system rail. Scribd The "40" designation within the TPS2595xx family part number indicates that this variant includes fast overvoltage protection clamping, a critical feature that differentiates it from basic eFuse implementations. Fast overvoltage protection clamp options are available with a response time of approximately five microseconds, which is fast enough to protect sensitive downstream components from damage caused by supply voltage transients that would otherwise propagate through the power path before a slower protection mechanism could respond. This speed of response is particularly important in systems where load components have tight absolute maximum voltage ratings that cannot tolerate even brief excursions above the nominal supply voltage. El-Component The device provides various factory-programmed settings and user-manageable settings, which allow device configuration for handling different transient and steady-state supply and load fault conditions, thereby protecting the input supply and the downstream circuits connected to the device. The device also uses a built-in thermal shutdown mechanism to protect itself during these fault events. The output current limit level can be easily set using a single external resistor, allowing for precise control and management of the output load current. Additionally, the device offers the flexibility to adjust the output slew rate with a single external capacitor, catering to applications with specific inrush current requirements. ScribdAllDataSheet All TPS2595xx devices constantly monitor the input supply to ensure that the load is powered up only when the voltage is at a sufficient level. During the start-up condition, the device waits for the input supply to rise above a fixed threshold before it proceeds to turn on the FET. Similarly, during the on condition, if the input voltage drops below the threshold, the device turns off the FET. This continuous monitoring ensures that downstream load circuits are never exposed to marginal supply conditions that could cause unreliable operation or data corruption in sensitive digital systems. Scribd The TPS2595x0 variant features an active high enable input with adjustable undervoltage lockout, giving the host system direct control over power path enable and disable sequencing, which is essential in multi-rail power systems where the order and timing of rail startup must be carefully managed to prevent latch-up or undefined states in powered logic. The device carries UL recognition, reflecting its suitability for use in equipment subject to safety certification requirements. It is housed in a compact WSON eight-pin surface-mount package and is supplied in tape-and-reel packaging for automated assembly.

LED Driver IC 16 Output Linear PWM Dimming 25mA 28-TSSOP The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 24 Hz to 1526 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value. All outputs are set to the same PWM frequency. Each LED output can be off or on (no PWM control), or set at its individual PWM controller value. The LED output driver is programmed to be either open-drain with a 25 mA current sink capability at 5 V or totem pole with a 25 mA sink, 10 mA source capability at 5 V. The PCA9685 operates with a supply voltage range of 2.3 V to 5.5 V and the inputs and outputs are 5.5 V tolerant. LEDs can be directly connected to the LED output (up to 25 mA, 5.5 V) or controlled with external drivers and a minimum amount of discrete components for larger current or higher voltage LEDs. The PCA9685 is in the new Fast-mode Plus (Fm+) family. Fm+ devices offer higher frequency (up to 1 MHz) and more densely populated bus operation (up to 4000 pF). Although the PCA9635 and PCA9685 have many similar features, the PCA9685 has some unique features that make it more suitable for applications such as LCD or LED backlighting and Ambilight: • The PCA9685 allows staggered LED output on and off times to minimize current surges. The on and off time delay is independently programmable for each of the 16 channels. This feature is not available in PCA9635. • The PCA9685 has 4096 steps (12-bit PWM) of individual LED brightness control. The PCA9635 has only 256 steps (8-bit PWM). • When multiple LED controllers are incorporated in a system, the PWM pulse widths between multiple devices may differ if PCA9635s are used. The PCA9685 has a programmable prescaler to adjust the PWM pulse widths of multiple devices. • The PCA9685 has an external clock input pin that will accept user-supplied clock (50 MHz max.) in place of the internal 25 MHz oscillator. This feature allows synchronization of multiple devices. The PCA9635 does not have external clock input feature. • Like the PCA9635, PCA9685 also has a built-in oscillator for the PWM control. However, the frequency used for PWM control in the PCA9685 is adjustable from about 24 Hz to 1526 Hz as compared to the typical 97.6 kHz frequency of the PCA9635. This allows the use of PCA9685 with external power supply controllers. All bits are set at the same frequency. • The Power-On Reset (POR) default state of LEDn output pins is LOW in the case of PCA9685. It is HIGH for PCA9635. #CommonPartsLibrary #IntegratedCircuit #PowerManagement

Power Supply Controller Digital Power Monitor 10-VSSOP The INA228 is an ultra-precise digital power monitor with a 20-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure a full-scale differential input of ±163.84 mV or ±40.96 mV across a resistive shunt sense element with common-mode voltage support from –0.3 V to +85 V. The INA228 reports current, bus voltage, temperature, power, energy and charge accumulation while employing a precision ±0.5% integrated oscillator, all while performing the needed calculations in the background. The integrated temperature sensor is ±1°C accurate for die temperature measurement and is useful in monitoring the system ambient temperature. The low offset and gain drift design of the INA228 allows the device to be used in precise systems that do not undergo multi-temperature calibration during manufacturing. Further, the very low offset voltage and noise allow for use in mA to kA sensing applications and provide a wide dynamic range without significant power dissipation losses on the sensing shunt element. The low input bias current of the device permits the use of larger currentsense resistors, thus providing accurate current measurements in the micro-amp range. The device allows for selectable ADC conversion times from 50 µs to 4.12 ms as well as sample averaging from 1x to 1024x, which further helps reduce the noise of the measured data. • High-resolution, 20-bit delta-sigma ADC • Current monitoring accuracy: – Offset voltage: ±1 µV (maximum) – Offset drift: ±0.01 µV/°C (maximum) – Gain error: ±0.05% (maximum) – Gain error drift: ±20 ppm/°C (maximum) – Common mode rejection: 154 dB (minimum) • Power monitoring accuracy: – 0.5% full scale, –40°C to +125°C (maximum) • Energy and charge accuracy: – 1.0% full scale (maximum) • Fast alert response: 75 μs • Wide common-mode range: –0.3 V to +85 V • Bus voltage sense input: 0 V to 85 V • Shunt full-scale differential range: ±163.84 mV / ±40.96 mV • Input bias current: 2.5 nA (maximum) • Temperature sensor: ±1°C (maximum at 25°C) • Programmable resistor temperature compensation • Programmable conversion time and averaging • 2.94-MHz high-speed I2C interface with 16 pinselectable addresses • Operates from a 2.7-V to 5.5-V supply: – Operational current: 640 µA (typical) – Shutdown current: 5 µA (maximum) #CommonPartsLibrary #IntegratedCircuit #PowerManagement
