1 MIC9452/ mΩ P-Channel MOSFET in SC-7-6 General escription The MIC9452/9453 are low on-resistance, 84mΩ(max) P-channel MOSFETs. They are housed in a Teeny SC- 7-6 package. esigned for high-side switch applications where space is critical, the MIC9452/3 exhibit a typical on-resistance of 7mΩ at 4.5V gate-to-source voltage. The devices operate down to 1.8V gate-to-source voltage. Their operating voltage range makes the MIC9452/3 ideal for Li Ion applications as well as other sub-5v load switch applications. The MIC9453 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 MIC9452/3 have a junction temperature range of 4 C to +15 C.
