The MIC94044YFL TR is a high-side Load Switch designed to operate from 1.7 to 5.5V input voltage. The load switch pass element is an internal 28mR RDSON P-channel MOSFET which enables the device to support up to 3A of continuous current. The MIC94044 provides a slew rate controlled soft-start turn-on of 1ms (typical) to prevent an in-rush current event from pulling down the input supply voltage. The enable voltage can be as high as 5.5V and is not limited by the input voltage. The MIC94044 operating voltage range makes them ideal for Lithium ion and NiMH/NiCad/Alkaline battery powered systems, as well as non-battery powered applications. The devices provide low quiescent current and low shutdown current to maximize battery life.
