Power Switch IC

The STMicroelectronics High voltage and high-speed half-bridge gate driver for GaN power switches 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 600 V 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.
