STMicroelectronics STDRIVEG212 220V Half-Bridge Gate Driver

STMicroelectronics STDRIVEG212 220V High-Speed Half-Bridge Gate Driver is optimized for 5V driving enhanced-mode GaN HEMTs. The high-side driver section is designed to support a voltage rail of up to 220V and can be easily supplied by the integrated bootstrap diode. High-current capability, short propagation delay with excellent delay matching, and integrated LDOs make the STDRIVEG212 optimized for driving high-speed GaN.

The STDRIVEG212 features supply UVLOs tailored to hard-switching applications, an overcurrent comparator with SmartSD, and interlocking to avoid cross-conduction conditions. The extended range of the input pins allows for easy interfacing with controllers. A standby pin provides for reducing the power consumption during inactive periods or in burst mode. The STMicroelectronics STDRIVEG212 operates within the industrial temperature range of -40°C to +125°C. The device is provided in a compact QFN package measuring 4mm x 5mm x 1mm with a 0.5mm pitch.
