MIC5021  
High-Speed High-Side MOSFET Driver  
General Description  
Features  
The MIC5021 high-side MOSFET driver is designed to oper-  
ate 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.  
• 12V to 36V operation  
• 550ns rise/fall time driving 2000pF  
• TTL compatible input with internal pull-down resistor  
• Overcurrent limit  
• Gate to source protection  
• Internal charge pump  
• 100kHz operation guaranteed over full temperature and  
operating voltage range  
• Compatible with current sensing MOSFETs  
• Current source drive reduces EMI  
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. TheMIC5021thensuppliesalimitedcurrent(< 2mA),  
if necessary, to maintain the output state.  
Applications  
Anovercurrentcomparatorwithatripvoltageof50mVmakes  
the MIC5021 ideal for use with a current sensing MOSFET.  
An external low value resistor may be used instead of a  
sensing MOSFET for more precise overcurrent control. An
