Description

The FPF1203 / 03L / 04 / 45 are ultra-small integrated IntelliMAX™ load switches with integrated P-channel switch and analog control features. Integrated slew- rate control prevents inrush current and the resulting excessive voltage drop on the power rail. The input voltage range operates from 1. 2 V to 5.5 V to provide power-disconnect capability for post-regulated power rails in portable and consum er products. The low shut- off current allows power designs to meet standby and off-power drain specifications. The FPF120x are controlled by a logic input (ON pin) compatible with standard CM OS GPIO circuitry found on Field Programmable Gate Array (FPGA) embedded processors. The FPF120x are available in 0.76 mm x 0.76 mm 4-bump WLCSP.
