Microchip High Side 1, Load Switch Power Switch IC 4-Pin, MLF

The MIC94040/1/2/3 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 28mΩ RDSON P-channel MOSFET which enables the device to support up to 3A of continuous current. The MIC94040 and MIC94041 feature rapid turn on, while the MIC94042 and MIC94043 provide a slew rate controlled softstart turn-on of 100μs. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage.
