DescriptionThe MIC94060 and MIC94061 are smart high-side load switches. MIC94060/94061 contain a low on-resistance, 77m Ohm (max) p-channel MOSFET that is driven by built-in level-shift and slew-rate control circuitry. The low on-resistance of the devices allows for them to support over 2A of cont...

Pull down circuitry keeps the MIC94060/1 in a default OFF state until the EN pin is pulled to a high level. The built-in level shift circuitry of MIC94060/94061 allows for a logic signal that may be different from the supply voltage to switch the high-side P-channel MOSFET on or off. The 1µs turn-on slew rate control prevents in-rush current from causing glitches on the supply rail.
Battery life of MIC94060/94061 is saved in portable applications with the IC's low quiescent current of 2µA and low shutdown current of <1µA. Their 1.8V to 5.5V operating voltage range makes the MIC94060/1 suitable for 1-cell Li Ion, 2- to 3-cell NiMH / NiCad / Alkaline, as well as other sub-5V input applications.
Integrating the level-shift and slew-rate control circuitry of MIC94060/94061 saves valuable board space and reduces component placement cost compared to discrete solutions.
The MIC94060/1 are housed in the the 1.2x1.6MLF® and Teeny™ SC-70-6 package and have a junction temperature range of 40°C to +150°C.
