The MIC94082YFT TR is a high-side Power Switch designed to operate from 1.7 to 5.5V input voltage. The load switch pass element is an internal 67mR RDSON P-Channel MOSFET which enables the device to support up to 1.5A of continuous current. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage. An active pull-down on the enable input keeps the MIC940802 in a default OFF state until the enable pin is pulled above 1.25V. 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 MIC94080/1/2/3/4/5 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.
