General Description

The AAT4295/97 SmartSwitch is a member of AnalogicTechs Application Specific Power MOSFET™ (ASPM™) product family. The AAT4295/97 is comprised of three/six low-side N-channel MOSFET switches that gate an applied load to ground. This device is intended for controlling RGB fashion lighting in portable products; it can also be used for a combination of general purposes where a load requires a low-side switch connection to ground. The AAT4295/97 simplifies design and layout limitations by eliminating the need for multiple GPIO control lines and discrete MOSFETs to control product features.
