The Si823H4CB-AS1 from Skyworks Solutions is an Automotive-Qualified Symmetric Gate Driver that combines two isolated gate drivers in a single package for high-power applications. It requires an input voltage of 3 – 5.5 V and an input current of less than 2.2 mA. This gate driver is suited for driving MOSFETs and IGBTs in a variety of switched power and motor control systems. It leverages Skyworks' silicon isolation technology that delivers an isolation voltage of 5 kV (RMS) for 1 minute, ensuring low delay, minimal skew, and consistent performance across varying temperatures and over time. This AEC-Q100-qualified gate driver IC is equipped with over-temperature protection (OTP), output under-voltage lockout (UVLO) fault detection, and fail-safe drivers that default to low in the event of input power loss. It offers a longer service life and significantly enhanced reliability compared to opto-coupled gate drivers.

This RoHS-compliant gate driver IC is available in a surface-mount package that measures 9.9 x 3.9 mm and is ideal for battery electric vehicles, hybrid electric vehicles, traction inverters, on-board chargers, charging stations, power delivery systems, motor control systems, isolated DC-DC power supplies, solar, and industrial inverter applications.
