The C0044BG400 series is an IGBT gate driver designed for high-reliability applications, featuring fiber-optic communication for switching commands and status feedback, an integrated DC/DC converter with soft start, and built-in EMI filtering. It provides a peak gate current of 44 A, with gate-on and gate-off voltages of +15 V and -15 V respectively, and operates within a temperature range of -20 to +55 °C. The driver includes Vce-desat protection with a trip threshold of 25 V, soft switch-off capability, and monitoring of all secondary supply voltages. A separate gate interface card enables optimal packaging, and partial discharge voltage withstand is rated up to 7 kV. Propagation delay is typically 1.4 μs, and coupling capacitance between primary and secondary is 16 to 20 pF.
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 .
