产品概览
The SI8234BB-D-IS1R from Skyworks Solutions (formerly Silicon Labs) is an automotive-grade dual-channel isolated gate driver with 4A peak output current and 2500 Vrms isolation. Using capacitive coupling technology with >20 kV/µs CMTI, it drives MOSFETs and IGBTs in half-bridge configurations for automotive and industrial power conversion. The D suffix indicates high-side/low-side configuration with overlapping protection. AEC-Q100 qualified in SOIC-16 wide body package.
