FN2853.6
Dual Power MOSFET Driver
Features
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.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
