Microchip | MIC94081YFT-TR

The MIC94081YFT TR is a part of MIC9408x series high-side load switch designed to operate from 1.7V to 5.5V input voltage. The load switch pass element is an internal 67 mO RDSON P-Channel MOSFET which enables the device to support up to 1.5 A 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.

The MIC94080 and MIC94081 feature rapid turn on. The MIC94082 and MIC94083 provide a slew rate controlled soft-start turn-on of 850µs, while the MIC94084 and MIC94085 provide a slew rate controlled soft-start turn-on of 120µs. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage.
