Microchip Technology MIC94162
The MIC94161, MIC94162, MIC94163, MIC94164, and MIC94165 are a family of high-side load switches designed to operate from 1.7V to 5.5V input voltage. The load switch pass element is an internal 14.5 mΩ RDS(ON) N-Channel MOSFET that enables the device to support up to 3A of continuous current. The MIC94161/2/3/4/5 provide reverse current protection when the device is disabled.FEATURES

GENERAL DESCRIPTION
Additionally, the load switch supports 1.5V logic level control and shutdown features in a tiny 1.5 mm × 1 mm 6-ball WLCSP package. The device will not allow the flow of current from the output to the input when the device is turned OFF. Additionally, the MIC94161 features overvoltage protection to protect the load when the input voltage is above 4.55V, as well as a precise enable threshold that keeps the MIC94161 in the default OFF state until the EN pin rises above 1.15V.
