It disconnects loads powered from the DC power rail (<6 V) with stringent off-state current targets and high load capacitances (<100 µF). The FPF2496 consists of a slew-rate controlled low-impedance MOSFET switch (100 mΩ maximum) and integrated analog Features . The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. FPF2496 has over-voltage and over-temperature protection. The FPF2496 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 µA maximum) facilitates pliance with standby power requirements. The input voltage range operates from 3.5 V to 5.5 VDC to support a wide range of applications in consumer, optical, medical, storage, portable, and industrial-device power management systems.
