Half Bridge Gate Driver (Isolated High Side & Non-Isolated Low Side)

Favorite

Overview

NCD57200 is a high voltage gate driver with one non−isolatedlow side gate driver and one galvanic isolated high or low side gatedriver. It can directly drive two IGBTs in a half bridge configuration.Isolated high side driver can be powered with an isolated power supplyor with Bootstrap technique from the low side power supply. The galvanic isolation for the high side gate driver guaranteesreliable switching in high power applications for IGBTs that operateup to 800 V, at high dv/dt. The optimized output stages provide a meanof reducing IGBT losses. Its features include two independent inputswith deadtime and interlock, accurate asymmetric UVLOs, and shortand matched propagation delays. The NCD57200 operates with itsVCC/VB up to 20 V.
