STMicroelectronics STDRIVEG611 Half-Bridge Gate Driver
STMicroelectronics STDRIVEG611 Half-Bridge Gate Driver is a high-voltage half-bridge gate driver for N-channel Enhancement Mode GaN. The high-side driver section is designed to stand a voltage rail up to 600V 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 STDRIVEG611 optimized for driving high-speed GaN.
The STMicroelectronics STDRIVEG611 features supply UVLOs tailored to hard switching applications, interlocking to avoid cross-conduction conditions, and an overcurrent comparator with SmartSD. The input pins' extended range allows easy interfacing with controllers. A standby pin reduces power consumption during inactive periods or burst mode. The STDRIVEG611 operates in the industrial temperature range of -40°C to 125°C. The device is available in a compact QFN 4mm x 5mm x 1mm package with a 0.5mm pitch.
