The C0044BG400SBT is an IGBT gate driver in the C0044BG400 series, designed for high-reliability applications with fiber-optic communication for command and feedback signals. It features an integrated DC/DC converter with soft start, input EMI filtering, and separate gate interface card for close IGBT coupling. The driver provides gate current up to 44 A, monitors all secondary supply voltages with defined power good/bad thresholds, and implements VCE-desat detection at 25 V with soft turn-off timing of 30 μs. It supports partial discharge voltage levels up to 7 kV, has primary-secondary coupling capacitance of 16-20 pF, and operates within a temperature range of -20 to +55 °C. The device meets the AEC-Q200 qualification standard and includes short-pulse suppression and low-light protection. Creepage distance from primary to secondary side exceeds 30 mm.
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 .
