STMicroelectronics STDRIVEG612
the STDRIVEG612 is a 600 V high-speed half-bridge gate driver optimized for 5 V driving enhanced-mode GaN HEMTs. The high-side driver section is designed to support a voltage rail up to 600 V and can easily be supplied by the integrated bootstrap diode. The STDRIVEG612 features supply UVLOs tailored to hard-switching applications, interlocking to avoid cross-conduction conditions and an overcurrent comparator with SmartSD.FEATURES
