Product Introduction
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 (<2 mA), if necessary, to maintain the output state.
An overcurrent comparator with a trip voltage of 50 mV makes 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 optional external capacitor placed from the CT pin to ground may be 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 CT to VDD. Additional parts of the MIC502x family include the MIC5020 low-side driver and the MIC5022 half-bridge driver with a cross-conduction interlock. The MIC5021 is available in 8-pin SOIC and plastic DIP packages.
