The C0044BG400 is an IGBT gate driver designed for high-reliability applications with fiber-optic input and output interfaces, integrated DC/DC converter, and Vce-desaturation protection. It provides a gate current of up to 44 A and operates with a primary supply voltage of 14.4 to 15.6 V. The driver features balanced propagation delay of 1.4 µs, soft-switch-off at fault conditions, and monitoring of all secondary supply voltages. A separate gate interface card enables close coupling to the IGBT, while partial discharge voltage ratings exceed 2.5 kV. Operating temperature ranges from -20 °C to +55 °C. The driver is part of a series compatible with various press-pack IGBTs, as indicated by customisation codes in Table 2.
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 .
