IntelliMAXt 28 V, Over-Voltage, Over-Current Protection Load Switch with Adjustable Current-Limit Control FPF2595 Description The FPF2595 advanced load−management switch targets applications requiring a highly integrated solution. It disconnects loads powered from the DC power rail (<6 V) with stringent off−state current targets and high load capacitances (<100 mF). The FPF2595 consists of a slew−rate controlled low−impedance MOSFET switch (35 mW typical) and integrated analog features. The slew−rate controlled turn−on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. FPF2595 has over−voltage protection and over− temperature protection. The FPF2595 has a True Reverse−Current Blocking (TRCB) function that obstructs unwanted reverse current from VOUT to VIN during ON and OFF states. The exceptionally low off−state current drain (<2 mA maximum) facilitates compliance with standby power requirements. The input voltage range operates from 2.5 V to 5.5 VDC to support a wide range of applications in consumer, optical, medical, storage, portable, and industrial−device power management. Switch control is managed by a logic input (active HIGH) capable of interfacing directly with low−voltage control signal / General−Purpose Input / Output (GPIO) without an external pull−down resistor. The device is packaged in advanced, fully “green” compliant, 1.3 mm x 1.8 mm, Wafer−Level Chip−Scale Packages (WLCSP).
