Description
The AUIRS4426 is a low voltage, high speed power MOSFET and IGBT driver. Proprietary latch immune
CMOS technologies enable ruggedized monolithic construction. The logic input is compatible with standard
CMOS or LSTTL output. The output drivers feature a high pulse current buffer stage designed for minimum
driver cross-conduction. Propagation delays between two channels are matched.
