MIC94002
Dual P-Channel MOSFET
Not Recommended for New Designs
General Description
The MIC94002 contains two silicon gate P-channel MOSFETs
designed for low on-resistance, high-side switch applica-
tions.
The MIC94002 has a maximum on-resistance of 0.4Ω at 4.5V
gate-to-source voltage. On-resistance can also be reduced
to half by connecting both MOSFETs in parallel.
Improved ESD protection is provided by the gate protection
network shown in the schematic diagram.
The MIC94002 is supplied in a low-profile version of the
8-lead SOIC package.
The MIC94002 can be assembled with the body not shorted
to the sources for use in analog switch applications. Contact
the factory for more information.
Features
• 15V minimum drain-to-source breakdown
• 0.4Ω maximum on-resistance at
4.5V gate-to-source voltage (each MOSFET)
• Functional at 2.7V gate-to-source voltage
• 0.063" maximum height
Applications
• High-side switch
• Power management
• Stepper motor control
• 1.8" PCMCIA disk drive VCC switch
