pg18_infineon_image1Infineon Logo

The IR442xxL is a family of low voltage, wide VCC range, power MOSFET and IGBT non-inverting gate drivers.

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 IR44272L includes an enable input with internal pull up. And the IR44273L also includes an additional gate drive OUT pin for flexible PCB layout.
