STMicroelectronics STDRIVEG210 Half-Bridge Gate Drivers

STMicroelectronics STDRIVEG210 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 STDRIVEG210 half-bridge gate drivers feature supply UVLOs tailored to fast startup and low-consumption soft-switching applications. The high-side regulator is characterized by a very short wake-up time to maximize the application efficiency during intermittent operation (burst mode). 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 DC/DC, AC/DC, resonant converters, synchronous rectification, UPS, adapters, LED lighting, and USB-C.
