Microchip MIC94041YFL-TR, 1High Side, High Side Power Switch IC

The microchip high-side Load Switch 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 soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage. Internal level shift circuitry allows low voltage logic signals to switch higher supply voltages. The enable voltage can be as high as 5.5V and is not limited by the input voltage. The devices provide low quiescent current and low shutdown current to maximize battery life.
