Description

The FPF1207/08 is an ultra-small integrated IntelliMAX™ load switch with integrated P-channel switch and analog control features. Integrated slew-rate control prevents inrush current and the resulting excessive voltage drop on power rail. The input voltage range operates from 1.2V to 4.0V to provide power-disconnect capability for post-regulated power rails in portable and consumer products. The low shut-off current of 1µA (maximum) allows power designs to meet standby and off-power drain specifications.
