Five/Six Channel Push/Pull I/O Expander

General Description
The AAT4296/98 SmartSwitch is a member of
AnalogicTech's Application Specific Power MOS-
FET (ASPM) product family. The AAT4296/98
is comprised of five/six push/pull output switches
that gate each respective output between a common
input supply and ground. This device is targeted for
I/O expansion applications, but can also be used for
a combination of general purposes to simplify power
switching with an off state load discharge.
The AAT4296/98 operates over an input voltage
range of 1.8V to 5.5V, making it ideal for battery-
powered applications. The state of each output
channel is controlled with a single GPIO via the
EN/SET pin using AnalogicTech's Simple Serial
Control (S
2
Cwire) interface. When EN/SET is
pulled to logic high, the device is enabled and con-
sumes 3μA of typical quiescent current. In the off
state, each output is pulled low to ground to affect
a logic low state for I/O expander or power switch-
ing applications; this circuit will act as a load dis-
charge function to rapidly turn off a load circuit.
Rated over the -40°C to +85°C temperature range,
the AAT4296 is offered in a Pb-free 8-pin SC70JW
package, and the AAT4298 is offered in both a Pb-
free 10-pin SC70JW and a Pb-free 12-pin
TSOPJW package.
