MIC5021 Micrel MIC5021 High-Speed High-Side MOSFET Driver General Description The MIC5021 high-side MOSFET driver is designed to operate at frequencies up to 100kHz (5kHz 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 2000pF MOSFET in approximately 550ns.
The MIC5021 then supplies a limited current ( 2mA), if necessary, to maintain the output...
