The NCD57200 is a high voltage gate driver with one non- isolated

low side gate driver and one galvanically isolated high or low side gate

driver. It can directly drive two IGBTs in a half bridge configuration.

Isolated high side driver can be powered with an isolated power supply

or with Bootstrap technique from the low side power supply.

The galvanic isolation for the high side gate driver guarantees

reliable switching in high power applications for IGBTs that operate

up to 800 V, at high dv/dt. The optimized output stages provide a mean

of reducing IGBT losses. Its features include two independent inputs

with deadtime and interlock, accurate asymmetric UVLOs, and short

and matched propagation delays. The NCD57200 operates with its

VDD/VBS up to 20 V.
