AAT4285
12V Slew Rate Controlled Load Switch
General Description
Features
SmartSwitch™
The AAT4285 SmartSwitch is a P-channel MOSFET
power switch designed for high-side load switching
applications. The MOSFET operates from a 3.0V to
13.2V input range making it ideal for applications in
single or dual cell Lithium-Ion battery systems. The
device has a typical RDS(ON) of 240mΩ at 12V, allow-
ing a low forward voltage drop and high current han-
dling capability. The device is a slew rate limited turn-
on load switch and is functionally compatible with the
AAT4250 and AAT4280 products, while offering a
high operating voltage. The AAT4285 features fast
load switch turn-on capability of 100µs and offers a
shutdown load discharge circuit to rapidly turn off a
load circuit when the switch is disabled. The quies-
cent supply current is very low, typically 25µA.
The AAT4285 is available in a Pb-free, 8-pin
SC70JW package and is specified over the -40°C
to +85°C temperature range.
