These SmartSwitch™ devices are members of AnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family. They are targeted for I/O expansion applications and 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 powered by Li-Ion batteries. These devices can also be used for general purpose power load switching.

To simplify switch implementation and reduce pin count, the state of each output channel is controlled with a single GPIO via the EN/SET pin using AnalogicTech's Simple Serial Control™ (S²Cwire™) one-wire interface. These devices have very low quiescent supply current significantly improving power efficiency.
