The C0044BG400 is an IGBT gate driver designed for high-reliability applications with fiber-optic communication for switching commands and feedback. It integrates a DC/DC converter with soft start, input EMI filtering, and separate gate interface card for optimal packaging. The driver delivers up to 44A gate current, monitors all secondary supply voltages, and supports Vce-desat detection with a 25V threshold. It features soft turn-off timing of 30 µs, low propagation delay of 1.4 µs, and a partial discharge voltage rating of at least 2.5 kV (up to 7 kV on request). The device operates from a primary supply voltage of 14.4 to 15.6 V and maintains a maximum operating temperature of +55 °C. It meets isolated creepage requirements of >30 mm between primary and secondary sides.
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 .
