MIC94083YFT-TR

The MIC94083 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 67m? RDSON P-Channel MOSFET which enables the device to support up to 2A 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 MIC94083 provide a slew rate controlled softstart turn-on of 800µs. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage. The MIC94083 feature an active load discharge circuit which switches in a 250? load when the switch is disabled to automatically discharge a capacitive load. An active pull-down on the enable input keeps the MIC94083 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 MIC94083 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.
