AAT4290/4291
I/O Expander Load Switches with Serial Control

General Description
The AAT4290 and AAT4291 SmartSwitch prod-
ucts 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 a Simple Serial Control
(S
2
Cwire) interface which permits ease of control
and efficiency of size. The quiescent supply cur-
rent is very low, typically 5μA. In shutdown mode,
the supply current is reduced to less than 1μA.
The AAT4290 and AAT4291 are offered in an 8 pin
SC70JW package specified over the -40°C to
+85°C temperature range.
