The C0044BG400 series is an IGBT gate driver designed for high-reliability applications, featuring fiber-optic communication for command and feedback signals, integrated DC/DC converter with soft start, and EMI filtering. It provides a peak gate current of 44 A and supports partial discharge voltages up to 7 kV. The driver monitors secondary supply voltages and IGBT switching status via Vce-desat detection with a typical trip level of 25 V, and employs soft turn-off timing of 30 μs under fault conditions. It operates within a temperature range of -20 to +55 °C and uses a separate gate interface card for optimal IGBT coupling. The unit 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 .
