General Description The AAT4618 SmartSwitch is a member of Skyworks' Application Specific Power MOSFET™ (ASPM™) product family. It is a current limited P-channel MOSFET power switch designed for high-side load switching applications operating with inputs ranging from 2.4V to 5.5V, making it ideal for 2.5V, 3V, and 5V systems. An integrated current-limiting circuit protects the input supply from large currents which may cause the supply to fall out of regulation. In addition, the AAT4618 thermal overload protection limits power dissipation and junction temperatures associated with prolonged periods of operation in current limit. Due to its low RDS(ON), the AAT4618 can be used to control loads that require up to factory preset 400mA, 500mA, or 1A.
