MIC5020  
Current-Sensing Low-Side MOSFET Driver  
General Description  
Features  
The MIC5020 low-side MOSFET driver is designed to oper-  
ate at frequencies greater than 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  
powersupplies),andapplicationsusing IGBTs. TheMIC5020  
canalsooperateasacircuitbreakerwithorwithoutautomatic  
retry. The MIC5020’s maximum supply voltage lends itself to  
control applications using up to 50V. The MIC5020 can  
control MOSFETs that switch voltages greater than 50V.  
• 11V to 50V operation  
• 175ns rise/fall time driving 2000pF  
• TTL compatible input with internal pull-down resistor  
• Overcurrent limit  
• Fault output indication  
• Gate to source protection  
• Compatible with current sensing MOSFETs  
Applications  
• Lamp control  
• Heater control  
• Motor control  
• Solenoid switching  
• Switch-mode power supplies  
• Circuit breaker  
A rising or falling edge on the input results in a current source  
orsinkpulseonthegateoutput. Thisoutputcurrentpulsecan  
turn on or off a 2000pF MOSFET in approximately 175ns.  
The MIC5020 then supplies a limited current (< 2mA), if  
necessary, to maintain the output state.  
Anovercurrentcomparatorwithatripvoltageof50mVmakes  
the MIC5020 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  
optional external capacitor connected to the C pin may be

Ordering Information  
used to control the current shutdown duty cycle from 20% to  
< 1%. A duty cycle from 20% to about 75% is possible with  
an optional pull-up resistor from C to V . An open collector
