Description
The FPF2496 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 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 compliance 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. Switch control is managed by a logic input
(active LOW) 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, 1.21 mm x 1.21 mm, Wafer-Level Chip-
Scale Package (WLCSP).
