The C0044BG400 is an IGBT gate driver designed for high-reliability applications with fiber-optic control and feedback, integrated DC/DC conversion, and V-CE desaturation detection. It features a separate gate interface card, a 44A peak gate current, and supports partial discharge voltages up to 7 kV. Operating temperature ranges from -20 °C to +55 °C, with a primary supply voltage of 14.4 to 15.6 V. Propagation delay is 1.4 µs, and soft turn-off time is 30 µs. The driver monitors all secondary supply voltages and includes short-pulse suppression and low-light protection. The unit uses a passive 20 kΩ gate resistor and has a primary-to-secondary
The C044BG400 IGBT Gate Driver is a low power consumption driver with on board VCE desaturation detection for high reliability application. The driver features a fiber-optic communication interface for drive, status and switching feedback signals. A fully supervised DC/DC converter with EMI filtering, low coupling capacitance and high partial discharge level is integrated into the board. The high voltage collector sense and gate interface are implemented on a separate card to allow close coupling to the IGBT. A range of pre-configured boards is available to complement the Littelfuse range of press-pack IGBTs – other applications on request. For additional technical details, please contact support .
