These SmartSwitch™ devices are members of Application Specific Power MOSFET™ (ASPM™) product family. They are intended for controlling RGB fashion lighting in portable products and operate with an input voltage ranging from 1.8V to 5.5V, making them ideal for 2.5V, 3.3V, or 5V systems. They can also be used for a combination of general purposes where a load requires a low-side switch connection to ground.
These devices simplify design and layout limitations by eliminating the need for multiple GPIO control lines and discrete MOSFETs to control product features. 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 Simple Serial Control™ (S²Cwire™) one-wire interface.
