MIC94061

The MIC94060 and MIC94061 are smart high-side load switches housed in the SC-70-6 package. The devices contain a low on-resistance, 100m(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 continuous current. The MIC94061 features an active pull-down circuit that discharges capacitive loads through a 200 switch when the IC is set to the OFF state.

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 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 1s turn-on slew rate control prevents in-rush current from causing glitches on the supply rail.

Battery life of MIC94061 is saved in portable applications with the IC's low quiescent current of 2A and low shutdown current of <1A. 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 saves
valuable board space and reduces component placement cost compared to discrete solutions. The MIC94060/1 are housed in the Teeny™ SC-70-6 package and have a junction temperature range of 40°C to +150°C.
