MIC5021
High-Speed, High-Side MOSFET Driver with Charge Pump
and Overcurrent Limit
Features General Description • 12V to 36V Operation
• 550 ns Rise/Fall Time Driving 2000 pF
• TTL-Compatible Input with Internal Pull-Down
Resistor
• Overcurrent Limit
• Gate-to-Source Protection
• Internal Charge Pump
• 100 kHz Operation Guaranteed Over Full Temperature and Operating Voltage Range
• Compatible with Current-Sensing MOSFETs
• Current-Source Drive Reduces EMI The MIC5021 high-side MOSFET driver is designed to
operate at frequencies up to 100 kHz (5 kHz PWM for
2% to 100% duty cycle) and is an ideal choice for high
speed applications such as motor control, SMPS
(switch mode power supplies), and applications using
IGBTs. The MIC5021 can also operate as a circuit
breaker with or without automatic retry.
A rising or falling edge on the input results in a current
source pulse or sink pulse on the gate output. This output current pulse can turn on a 2000 pF MOSFET in
approximately 550 ns. The MIC5021 then supplies a
limited current (
