MIC94052/94053
84m P-Channel MOSFET in SC-70-6 Final
General Description
The MIC94052/94053 are low on-resistance, 84m(max) Pchannel MOSFETs. They are housed in a TeenyTM 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 pullup 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 -40C to +150C.

TA = 25C unless otherwise noted. Absolute maximum ratings indicate limits beyond which damage to the component may occur. Electrical specifications do not apply when operating the device outside of its operating ratings. This device is not guaranteed to operate beyond its specified operating rating. Mounted on 1 square-inch pad of 2 oz. copper. IC devices are inherently ESD sensitive. Handling precautions required. Pulse test; pulse width = 300s, duty cycle = 2%. Guaranteed by design. Body diode current conduction is not recommended. Ensure that all drain pins are connected together to optimize RDS(ON) perfomance.
