ICL7667

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 capacitive loads with high slew 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 switched-mode 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.

*Pb-free PDIPs can be used for through hole wave solder processing

only. They are not intended for use in Reflow solder processing ap-

plications.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow tempera-

tures that meet or exceed the Pb-free requirements of IPC/JEDEC J

STD-020.
