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

IC SURGE STOPPER 2.7V~23V VQFN-10-HR(2x2) The TPS25947xx family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short-circuits, voltage surges, reverse polarity and excessive inrush current. With integrated back-to-back FETs, reverse current flow from output to input is blocked at all times, making the devices an excellent choice for power MUX/ORing applications as well as systems which need load side energy hold up storage in case input power supply fails. The devices use linear ORing based scheme to establish an almost zero DC reverse current and emulate ideal diode behavior with minimum forward voltage drop and power dissipation. Output slew rate and inrush current can be adjusted using an external capacitor. Loads are protected from input overvoltage conditions either by clamping the output to a safe fixed maximum voltage (pin selectable), or by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current or breaking the circuit. The output current limit threshold as well as the transient overcurrent blanking timer are user adjustable. The current limit control pin also functions as an analog load current monitor. The devices are available in a 2mm × 2mm, 10- pin HotRod™ QFN package for improved thermal performance and reduced system footprint.
