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 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 continuous current. The MIC94061 features an active pull-down circuit that discharges capacitive loads through a 200 Ohm 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 1µs turn-on slew rate control prevents in-rush current from causing glitches on the supply rail.

Battery life 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 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.
