AAT4290/91
I/O Expander Load Switches with Serial Control
General Description
The AAT4290 and AAT4291 SmartSwitch products
are members of AnalogicTech’s Application
Specific Power MOSFET™ (ASPM™) product
family. The AAT4290 and AAT4291 are five and
three P-channel MOSFETs, respectively, config-
ured for use as a microprocessor I/O expander.
Having independent drain outputs and a common
source input, they operate with an input voltage
ranging from 1.8V to 5.5V, making them ideal for
2.5V, 3.3V, or 5V systems, as well as systems pow-
ered by lithium-ion/polymer batteries. Each switch
features a 500ns turn-on time. The switch states
are controlled by AnalogicTech’s Simple Serial
Control™ (S2Cwire™) interface which permits ease
of control and efficiency of size. The quiescent
supply current is very low, typically 5µA. In shut-
down mode, the supply current is reduced to less
than 1µA.
The AAT4290 and AAT4291 are offered in a Pb-
free, 8-pin SC70JW package specified over the
-40°C to +85°C temperature range.
