AUIRS4427S
Description
The AUIRS4427S 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.

Absolute Maximum Ratings
Absolute Maximum Ratings indicate sustained limits beyond which damage to the device may occur. All voltage
parameters are absolute voltages referenced to COM. The thermal resistance and power dissipation ratings are
measured under board mounted and still air conditions.
