Description
The MIC94080/1/2/3/4/5 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 67 mΩ (ON) P-Channel MOSFET that 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 0.85 mm x 0.85 mm 4-lead FTDFN package.
The MIC94080 and MIC94081 feature rapid turn on. The MIC94082 and MIC94083 provide a slew rate controlled soft-start turn-on of 800 μs, while the MIC94084 and MIC94085 provide a slew rate controlled soft-start turn-on of 120 us. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage.
The MIC94081, MIC94083, and MIC94085 feature an active load discharge circuit which switches in a 2500Ω load when the switch is disabled to automatically discharge a capacitive load.
An active pull-down on the enable input keeps the MIC94080/1/2/3/4/5 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.
