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.
The FPF1207/08 is controlled by an active-HIGH logic
input (ON pin) compatible with standard CMOS GPIO
circuitry found on Field Programmable Gate Array
(FPGA) and embedded processors. The FPF1207/08 is
available in 0.76mm x 0.76mm 4-bump WLCSP.
Applications
ƒ Mobile Devices and Smart Phones
ƒ Portable Media Devices
ƒ Ultra-Portable / Mobile Computing
ƒ Advanced Notebook, UMPC, MID
ƒ Portable Medical Devices
ƒ GPS and Navigation Equipment
