The AAT4296/98 SmartSwitch is a member of AnalogicTech's Application Specific Power MOSFET™ (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™ (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. The AAT4296 is offered in a Pb-free 8-pin SC70JW package, and the AAT4298 is offered in a Pb-free 12-pin TSOPJW package. Both devices are rated over the -40°C to +85°C temperature range.
