Product Information

MIC94030/94031 Micrel MIC94030/94031 TinyFET™ P-Channel MOSFET Preliminary Information 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 0.75Ω 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. The 4-terminal SOT-143 package permits a substrate connection separate from the source connection. This 4-terminal configuration improves the θJA (improved heat dissipation) and makes analog switch applications practical. The small size, low threshold, and low RDS(on) make the MIC94030/1 the ideal choice for PCMCIA card sleep mode or distributed power management applications.
