Half-Bridge MOSFET Driver

General Description

Features

The MIC5022 half-bridge MOSFET driver is designed to

operate 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 and SMPS (switch mode

power supplies).

• 12V to 36V operation

• 600ns rise time into 1000pF (high side)

• TTL compatible input with internal pull-down resistor

• Outputs interlocked to prevent cross conduction

• TTL compatible enable

• Fault output indication

• Individual overcurrent limits

• Gate protection

• Internal charge pump (high-side)

• Current source drive scheme reduces EMI

A rising or falling edge on the input results in a current source

pulse or sink pulse on the gate outputs. This output current

pulse can turn on a 2000pF MOSFET in approximately 1µs.

The MIC5022 then supplies a limited current (< 2mA), if

necessary, to maintain the output states.

Applications

• Motor control

• Switch-mode power supplies

Two overcurrent comparators with nominal trip voltages of

50mV make the MIC5022 ideal for use with current sensing

MOSFETs. Externallowvalueresistorsmaybeusedinstead

of sensing MOSFETs for more precise overcurrent control.

Optional external capacitors placed on the C and C pins

may be used to individually control the current shutdown duty

cycles from approximately 20% to <1%. Duty cycles from

20% to about 75% are possible with individual pull-up resis-

tors from C and C to V . An open collector output

Ordering Information

provides a fault indication when either sense input is tripped.
