AAT4298
AAT4298 is Five/Six Channel Push/Pull I/O Expander manufactured by AAT.
Five/Six Channel Push/Pull I/O Expander General Description
The AAT4296/98 Smart Switch is a member of Analogic Tech's Application Specific Power MOSFET™ (ASPM™) product family. The AAT4296/98 is prised of five/six push/pull output switches that gate each respective output between a mon input supply and ground. This device is targeted for I/O expansion applications, but can also be used for a bination 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 batterypowered applications. The state of each output channel is controlled with a single GPIO via the EN/SET pin using Analogic Tech's Simple Serial Control™ (S2Cwire™) interface. When EN/SET is pulled to logic high, the device is enabled and consumes 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 switching applications; this circuit will act as a load discharge function to rapidly turn off a load circuit.
