General Description

The MIC94080/1/2/3/4/5 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 67mΩ RDSON P-Channel MOSFET which enables the device to support up to 2A of continuous current. Additionally, the load switch supports 1.5V logic level control and shutdown features in a tiny 0.85mm x 0.85mm 4-pin Thin MLF® package.
