Data Sheet April 1999
Dual Power MOSFET Driver
The ICL7667 is a dual monolithic high-speed driver
designed to convert TTL level signals into high current
outputs at voltages up to 15V. Its high speed and current
output enable it to drive large capacitiveloadswithhighslew
rates and low propagation delays. With an output voltage
swing only millivolts less than the supply voltage and a
maximum supply voltage of 15V, the ICL7667 is well suited
for driving power MOSFETs in high frequency switchedmode power converters. The ICL7667’s high current outputs
minimize power losses in the power MOSFETs by rapidly
charging and discharging the gate capacitance. The
ICL7667’s inputs are TTL compatible and can be directly
driven by common pulse-width modulation control ICs.
