Gate drive supply range from 5V to 20V
Undervoltage lockout for both channels
3.3V, 5V and 15V input logic compatible
Matched propagation delay for both channels
Outputs in phase and inputs
Lower di/dt gate driver for better noise immunity

Advantages
The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction while the floating channel can be used to drive an N-channel power MOSFET or IGBT in the high-side configuration which operates up to 600V.
The logic input is compatible with standard CMOS or LSTTL output down to 3.3V logic.
The IC features negative voltage spike (Vs) immunity to protect the system against catastrophic events during high-current switching and short circuit conditions.
