The C0044BG400 series is an IGBT gate driver designed for high-reliability applications with fiber-optic communication for switching commands and status feedback. It integrates a DC/DC converter with soft start, EMI filtering, and monitoring of all secondary supply voltages. The driver provides a peak gate current of 44 A, a partial discharge voltage up to 7 kV, and a propagation delay of 1.4 µs. It features Vₓₑ-desat detection with a threshold of 25 V, soft turn-off timing of 30 µs, and a separate gate interface card for optimal IGBT coupling. The operating temperature range is -20 to +55 °C, and the primary supply voltage is 14.4 to 15.6 V. The unit includes low coupling capacitance, balanced propagation delay, and short-pulse suppression. The C0044BG400SCB variant is configured for use with the T0600NC17A IGBT.
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 .
