MIC94030 General Description
The MIC94030 and MIC94031 are 4-terminal silicon gate P-channel MOSFETs that provide low on-resistance in a very
small package.
Designed for high-side switch applications where space is critical, the MIC94030/1 exhibits an on-resistance of typically 0.75W at 4.5V gate-to-source voltage.The MIC94030/1 also operates with only 2.7V gate-to-source voltage.
The MIC94030 is the basic 4-lead P-channel MOSFET. The MIC94031 is a variation that includes an internal gate pull-up resistor that can reduce the system parts count in many applications.
