MIC94030/94031
TinyFETВ® P-Channel MOSFET General Description Features 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 4terminal configuration improves the ОёJA (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. 13.5V minimum drain-to-source breakdown 0.75Ω typical on-resistance
