The FPF1048B advanced load management switch targets applications requiring a highly integrated solution. It disconnects loads powered from the DC power rail (<6V) with stringent off-state current targets and high load capacitances (up to 100µF). The FPF1048B consists of slew-rate controlled low-impedance MOSFET switch (23mΩ typical) and integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails.
The FPF1048B has a True Reverse Current Blocking (TRCB) function that obstructs unwanted reverse current from VOUT to VIN during both ON and OFF states. The exceptionally low off-state current drain (<1µA maximum) facilitates compliance with standby power requirements. The input voltage range operates from 1.5V to 5.5VDC 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, 1.0mm x 1.5mm, Wafer-Level Chip-Scale Package (WLCSP) with backside lamination.
