  • Description

    The Fuji EXB840 is a high-performance IGBT gate drive hybrid IC engineered to deliver reliable, isolated drive signals to IGBT modules used in medium and high-power conversion systems. Integrating gate drive amplification, overcurrent detection, and fault signaling into a single compact package, the EXB840 simplifies drive circuit design and enhances system protection. It operates from a single supply and provides the necessary gate voltage swing to turn IGBT devices on and off with low switching losses and controlled dV/dt characteristics.

    The EXB840 is widely deployed in industrial variable-speed motor drives, AC servo drives, uninterruptible power supplies (UPS), inverter-based welding equipment, and renewable energy converters including solar inverters and wind turbine control stages. Its robust overcurrent protection function responds rapidly to fault conditions, minimizing the risk of IGBT desaturation damage and improving overall system reliability in demanding environments.
