MIC94050/94051
4-Terminal SymFET P-Channel MOSFET
General Description
The MIC94050 and MIC94051 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 MIC94050/1 exhibits an on-resistance of typically
0.125Ω at 4.5V gate-to-source voltage.The MIC94050/1 also
operates with only 1.8V gate-to-source voltage.
The MIC94050 is the basic 4-lead P-channel MOSFET. The
MIC94051 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 con-
nection separate from the source connection. This 4-terminal
conguration improves the θJA (improved heat dissipation)
and makes reverse-blocking switch applications practical.
The small size, low threshold, and low RDS(on) make the
MIC94050/1 the ideal choice for PCMCIA, USB, back-up
battery-power, and distributed power management applica-
tions.
