mic94066-69 dual high side power switches mlf and micro lead frame is a registered trademark of amkor technologies micrel inc. 2180 fortune drive san jose, ca 95131 usa tel +1 ( 408 ) 944-0800 fax + 1 (408) 474-1000 http://www.micrel.com general description the mic94066-69 are dual high-side load switches designed for operation between 1.7v to 5.5v. the devices contain a pair of low on-resistance, 115m ? (max) p-channel mosfets that support over 2a of continuous current. the mic94067 and mic94069 feature an active load discharge circuit which insures capacitive loads retain no charge when the main switch is in an off state. an active pull-down on the enable input keeps mic94066-69 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. mic94066-67 feature rapid turn on while mic94068- 69 provide a slew rate controlled soft-start turn-on of 800s (typical) to prevent in-rush current from glitching supply rails. mic94066-69s voltage range makes them suitable for 1-cell lithium ion and 2- to 3-cell nimh/nicad/alkaline powered systems, as well as all 5v applications. their low operating current of 2a and low shutdown current of <1a maximize battery life. data sheets and support documentation can be found on micrels web site at www.micrel.com. features ? 1.7v to 5.5v input voltage range ? 2a continuous operating current ? 85m ?
