The MIC94161/2/3/4/5 is 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 14.5mΩ RDSON N-Channel MOSFET which enables the device to support up to 3A of continuous current.

Additionally, the load switch supports 1.5V logic level control and shutdown

in a tiny 1.5mm × 1mm 6-ball WLCSP package. The MIC9416x provides reverse current protection when the device is disabled. 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 which keeps the MIC94161 in the default OFF state until the EN pin rises above 1.15V. The MIC94161/2/3/4/5 operating.
