Overview
The NCV57200DR2G, produced by onsemi, is a high-voltage gate driver designed for driving two IGBTs in a half-bridge configuration. This device features one non-isolated low-side gate driver and one galvanic isolated high or low-side gate driver. The galvanic isolation ensures reliable switching in high-power applications, supporting IGBTs that operate up to 800 V. The NCV57200DR2G is optimized for reducing IGBT losses and includes features such as deadtime and interlock logic, accurate asymmetric under-voltage lockout (UVLO) thresholds, and matched propagation delays.
