Microchip Technology MIC94164YCS-TR

Description
The MIC94161/2/3/4/5 is a family of high-side load switches designed for operation from 1.7V to 5.5V input voltage. The load switch pass element is an internal 14.5mΩSON N-Channel MOSFET, enabling the device to support up to 3A of continuous current. Additionally, the load switch supports 1.5V logic level control and shutdown features in a tiny 1.5mm x 1mm 6-ball WLCSP package.
The MIC9416x provides reverse current protection when the device is disabled, preventing current flow from the output to the input. 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 device in the default OFF state until the EN pin rises above 1.15V.
