june 2008 1 m9999-060508 mic94052/53 mic94052/94053 84m ? p-channel mosfet in sc-70-6 general description the mic94052/94053 are low on-resistance, 84m ? (max) p-channel mosfets. they are housed in a teeny ? sc- 70-6 package. designed for high-side switch applications where space is critical, the mic94052/3 exhibit a typical on-resistance of 70m ? at 4.5v gate-to-source voltage. the devices operate down to 1.8v gate-to-source voltage. their operating voltage range makes the mic94052/3 ideal for li ion applications as well as other sub-5v load switch applications. the mic94053 is an option that includes an internal gate pull- up resistor. the pull-up resistor ensures that the p-channel mosfet is off until actively pulled down. integrating the pull-up resistor saves valuable board space and reduces component placement cost. the mic94052/3 have a junction temperature range of C40c to +150c. typical application off (high) s on (low) v in mic94053 4 3 g d1, 2, 5, 6 load load switch application features ? 1.8v to 5.5v input voltage range ? low on-resistance p-channel mosfet: 70m ? at v gs = 4.5v (typ) 2a continuous current ? v gs pull-up resistor (mic94053) ? teeny ? sc-70-6 package ?
