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),  
andapplicationsusingIGBTs.TheMIC5021canalsooperate  
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  
Arising or falling edge on the input results in a current source  
pulse or sink pulse on the gate output. This output current  
pulsecanturnona2000pFMOSFETinapproximately550ns.  
The MIC5021 then supplies a limited current (< 2mA), if  
necessary, to maintain the output state.  
Applications  
• Lamp control  
• Heater control  
• Motor control  
• Solenoid switching  
• Switch-mode power supplies  
• Circuit breaker  
Anovercurrentcomparatorwithatripvoltageof50mVmakes  
theMIC5021idealforusewithacurrentsensingMOSFET.An  
external low value resistor may be used instead of a sensing  
MOSFET for more precise overcurrent control. An optional  
external capacitor placed from the C pin to ground may be  
T
used to control the current shutdown duty cycle (dead time)  
from 20% to < 1%. A duty cycle from 20% to about 75% is  
possible with an optional pull-up resistor from C to V
