Description
The IR44272L is a low-voltage, wide VCC range, power MOSFET and IGBT non-inverting gate driver. Proprietary
latch immune CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with
standard CMOS or LSTTL output. The output driver features a current buffer stage. The design also includes an
enable input with internal pull up.
