Description
The FPF1205/06 is an ultra-small IntelliMAX^™ load
switch with integrated P-channel switch and analog
control features. Internal 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 FPF1205/06 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 FPF1205/06 is
available in a 0.76mm x 0.76mm 4-bump Wafer-Level
Chip-Scale Package (WLCSP).
Applications
ƒ Mobile Devices and Smart Phones
ƒ Portable Media Devices
