FPF2495CUCX集成电路（IC）的配电开关负载驱动器规格书PDF中文资料

Description

The FPF2495C 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 F). The FPF2495C

consists of a slew−rate controlled low−impedance MOSFET switch

(100 m maximum) and integrated analog features. The slew−rate

controlled turn−on characteristic prevents inrush current and the

resulting excessive voltage droop on power rails. FPF2495C has

over−voltage protection and over−temperature protection.

The FPF2495C 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 A 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,

1.21 mm x 1.21 mm, Wafer−Level Chip−Scale Package (WLCSP).
