特性和应用

The MIC5020YM low-side MOSFET driver is designed to operate at frequencies greater than 100 kHz (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 MIC5020 can also operate as a circuit breaker with or without automatic retry.

The MIC5020’s maximum supply voltage lends itself to control applications using up to 50 V. The MIC5020 can control MOSFETs that switch voltages greater than 50 V. A rising or falling edge on the input results in a current source or sink pulse on the gate output. This output current pulse can turn on or off a 2000 pF MOSFET in approximately 175 ns. The MIC5020 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 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 CT pin may be 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 CT to VDD. An open collector output provides a fault indication when the sense inputs are tripped. The MIC5020 is available in 8-pin SOIC and plastic DIP packages. Other members of the MIC502x series include the MIC5021 high-side driver and the MIC5022 half-bridge driver with a cross-conduction interlock.
