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 θ

dissipation)

practical.

The small size, low threshold, and low R

MIC94030/1 the ideal choice for PCMCIA card sleep mode

or distributed power management applications.
