STMicroelectronics STDRIVEG610 Half-Bridge Gate Drivers
STMicroelectronics STDRIVEG610 Half-Bridge Gate Drivers are high-performance devices designed for driving N-channel MOSFETs or IGBTs in a variety of power conversion applications. The STMicroelectronics STDRIVEG610 features a single input control and bootstrap operation, enabling efficient high-side and low-side switching with minimal external components. The devices support up to 600V on the high-side driver and include under-voltage lockout (UVLO) protection on both the low-side and high-side to ensure safe operation. With a typical propagation delay of 50ns and matched delay times, the STDRIVEG610 ICs are well-suited for high-frequency switching applications such as motor control, power supplies, and inverters. The compact design, robust protection features, and wide operating voltage range make the STDRIVEG610 Half-Bridge Gate Drivers a reliable choice for designers seeking efficient and compact gate driver solutions.
