The C0044BG400 is an IGBT gate driver designed for high-reliability applications, featuring fiber-optic communication for control and feedback, a built-in DC/DC converter with soft start, and integrated EMI filtering. It provides a peak gate current of 44 A, supports partial discharge voltages up to 7 kV, and offers Vce desaturation detection with a typical trip level of 25 V. The driver includes monitoring of all secondary supply voltages and a soft turn-off sequence of 30 μs when a fault is detected. It operates within a temperature range of -20 °C to +55 °C and maintains a propagation delay of 1.4 μs. The device uses a separate gate interface card and is configured for use with specific press-pack IGBTs, as indicated by its customisation code suffix.
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 .
