IntelliMAX™ Ultra-Small, Slew-Rate-Controlled Load Switch

The FPF1204 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 the power rail. The input voltage range operates from 1.2V to 5.5V 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. The FPF1204 is controlled by an active-HIGH logic input (ON pin) compatible with standard CMOS GPIO circuitry found on Field Programmable Gate Array (FPGA) embedded processors. The FPF1204 is available in 0.76mm x 0.76mm 4-bump WLCSP.
