STMicroelectronics STDRIVEG211 Half-Bridge Gate Drivers

STMicroelectronics STDRIVEG211 Half-Bridge Gate Drivers are designed for N‑channel enhancement mode GaN, and the high-side driver section can withstand a voltage rail up to 220V. These drivers feature high current capability, short propagation delay with excellent delay matching, and integrated LDOs. This makes them optimized for driving high-speed GaN. The STDRIVEG211 half-bridge gate drivers feature supply UVLOs tailored to hard switching applications, interlocking to avoid cross-conduction conditions, and an overcurrent comparator with SmartSD. These drivers offer an extended range for input pins that allows easy interfacing with controllers. A standby pin allows for reducing the power consumption during inactive periods or burst mode. Applications include solar micro inverters, Class D audio amplifiers, E-bikes, LED lighting, USB-C, power tools, and robotics.
