FPF1203 / FPF1204 / FPF12045 IntelliMAXTM Ultra-Small, Slew-Rate-Controlled Load Switch Features Description 1.2V to 5.5V Input Voltage Operating Range Slew Rate Control with tR: FPF1203/FPF1204: 100s FPF12045: 2s The FPF1203 / 04 / 45 are ultra-small integrated IntelliMAXTM 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 1.2V to 5.5V to provide power-disconnect capability for post-regulated power rails in portable and consumer products. The low shutoff current of 1A (maximum) allows power designs to meet standby and off-power drain specifications. Typical RON: 45m at VIN=5.5V 55m at VIN=3.3V 90m at VIN=1.8V 185m at VIN=1.2V The FPF1203 / 04 / 45 are 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 FPF1203 / 04 / 045 are available in 0.76mm x 0.76mm 4-bump WLCSP.
