NTE7226
Integrated Circuit
High Voltage, High Speed MOSFET/IGBT Driver
w/High and Low Side Outputs
14−Lead DIP Type Package
Description:
The NTE7226 is a high voltage, high speed power MOSFET and IGBT driver with independent high
and low side referenced output channels in a 14−Lead DIP type package. HVIC and latch immune
CMOS technologies enable ruggedized monolithic construction. Logic inputs are compatible with
standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse current
buffer stage designed for minimum driver cross−conduction. Propagation delays are matched to simplify use in high frequency applications. The floating channel can be used to drive an N−Channel
power MOSFET or IGBT in the high side configuration which operates up to 500 volts.

Note 2. For proper operation, the device should be used within the recommended conditions. The
VS and VSS offset ratings are tested with all supplies biased at 15V differential.
Note 3. Logic operational for VS of −4V to +500V. Logic state held for VS of −4V to −VBS.
Note 4. When VDD < 5V, the minimum VSS offset is limited to −VDD.
