MIC94030/94031
TinyFET ? P-Channel MOSFET
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 0.75 ? 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.
Features
? 13.5V minimum drain-to-source breakdown
? 0.75 ? typical on-resistance
– at 4.5V gate-to-source voltage
? 0.45 ? typical on-resistance
– at 10V gate-to-source voltage
? Operates with 2.7V gate-to-source voltage
? Separate substrate connection for added control
? Industry’s smallest surface mount package
Applications
The 4-terminal SOT-143 package permits a substrate
connection separate from the source connection. This 4-
terminal configuration improves the θ JA (improved heat
dissipation) and makes analog switch applications
practical.
The small size, low threshold, and low R DS(on) make the
MIC94030/1 the ideal choice for PCMCIA card sleep mode
or distributed power management applications.
