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.

Electronic Fuse Regulator 4A 8-WSON (2x2) The TPS259530DSGR is a compact, integrated eFuse protection device designed to provide robust power-path management for low-voltage DC systems, particularly nominal five-volt rails. It combines multiple protection and control features into a single solution, enabling safe distribution of power to downstream circuitry while minimizing the need for external components. The device supports controlled inrush current during startup, continuous current monitoring, and rapid fault response to protect both the power source and the load. Integrated protection mechanisms include overvoltage protection, undervoltage lockout, overcurrent limiting, thermal shutdown, and reverse current blocking. This makes the device well suited for applications requiring high reliability, such as embedded systems, industrial electronics, consumer devices, and communication equipment. Functional Description The device operates as a high-side protection switch using an internal MOSFET to control current flow from the input supply to the load. It monitors input voltage, output current, and internal temperature to ensure operation within safe limits. When a fault condition such as overcurrent or overvoltage is detected, the device limits or interrupts current flow to prevent damage. The integrated control loop provides smooth startup by limiting inrush current and preventing supply droop. Reverse current blocking prevents unwanted current flow from the output back to the input when the input supply is removed or drops below the output level. Electrical Characteristics The device supports operation across a wide input voltage range suitable for low-voltage DC systems, including typical five-volt rails. It features an adjustable overvoltage protection threshold aligned with five-volt system requirements, along with configurable undervoltage lockout to ensure proper system startup and shutdown behavior. The current limit is externally programmable, allowing flexibility for different load conditions. The device exhibits low on-resistance to minimize power dissipation and voltage drop during normal operation. Protection Features The TPS259530DSGR integrates multiple protection functions to enhance system robustness. Overvoltage protection prevents excessive input voltage from reaching the load. Undervoltage lockout ensures the device only operates when the input supply is within a valid range. Overcurrent protection actively limits current during fault conditions and can respond rapidly to short circuits. Thermal shutdown protects the device from overheating by disabling operation when internal temperature exceeds safe limits. Reverse current blocking prevents backflow of current, safeguarding both the source and load. Control and Interface The device includes an enable control input that allows external control of the power path. It supports configurable behavior for fault response and recovery, depending on system design. External components can be used to set thresholds such as current limit and undervoltage lockout, providing design flexibility. Status signaling allows system-level monitoring of fault conditions. Mechanical and Package Information The TPS259530DSGR is provided in a compact surface-mount package suitable for space-constrained applications. The package is optimized for thermal performance and efficient PCB layout, enabling reliable operation under varying load conditions. It is supplied in tape-and-reel format for automated assembly processes. Applications This device is intended for use in systems requiring reliable power distribution and protection. Typical applications include five-volt power rails in embedded systems, industrial control modules, consumer electronics, communication devices, and peripheral power management circuits. Summary The TPS259530DSGR offers an integrated, high-reliability solution for power path protection and management in low-voltage systems. Its combination of protection features, configurability, and compact form factor makes it a widely used choice for safeguarding five-volt supply rails in modern electronic designs. #commonpartslibrary #integratedcircuit #powermanagement
