7Semi UCC21330 Dual-channel Isolated Gate Driver Breakout
The 7Semi UCC21330 Dual-Channel Isolated Gate Driver Breakout is a high-performance module designed for driving power MOSFETs, IGBTs, and SiC/GaN transistors in high-voltage and high-speed switching applications. Based on Texas Instruments’ UCC21330, it features two fully isolated gate drivers with reinforced isolation up to 5.7 kVRMS and robust protection features, including under-voltage lockout (UVLO) and fault diagnostics. The breakout provides superior switching performance, low propagation delay, and high common-mode transient immunity (CMTI), making it ideal for motor control, power conversion, and industrial automation systems.
