Product Description

The Si823H7BB-IS1R is a high-performance Si823H7BB isolated driver designed as a dual-channel isolator chip for power electronics applications. It integrates two independent high-speed gate driver IC channels, each supporting input-to-output isolation up to 5 kV RMS, enabling robust operation in high-voltage environments. With a wide supply voltage range of 3.0 V to 5.5 V on the input side and 8 V to 30 V on the output side, it drives MOSFETs or IGBTs efficiently. Operating at temperatures from -40°C to +125°C, it suits industrial motor drives, renewable energy systems, and automotive inverters. Its high-speed switching (up to 1 MHz) and low propagation delay (40 ns typical) enhance system responsiveness. The dual-channel isolation ensures minimal crosstalk, while its compact package saves board space. A key limitation is the absence of integrated communication interfaces, requiring external control logic. The device excels in reliability and noise immunity but requires careful PCB layout for optimal EMI performance.
