MIC94001
P-Channel MOSFET
Not Recommended for New Designs
General Description
The MIC94001 is a silicon gate P-channel MOSFET de-
signed for low on-resistance, high-side switch applications.
The MIC94001 has a maximum on-resistance of 0.4鈩?at 4.5V
gate-to-source voltage.
Improved ESD protection is provided by the gate protection
network shown in the schematic diagram.
The MIC94001 is supplied in a low-profile version of the
8-lead SOIC package.
The MIC94001 die can be assembled in a 4-terminal configu-
ration with the body not shorted to the source for use in analog
switch applications. Contact the factory for more information.
