The C0044BG400 is an IGBT gate driver with fiber-optic interface, integrated DC/DC converter, and Vce-desat protection set to 25 V typical. It delivers a peak gate current of 44 A with +15 V gate-on and -15 V gate-off voltages, and a 1.4 μs propagation delay. Soft turn-off time is 30 μs, with passive gate resistor of 20 kΩ. Primary supply voltage ranges from 14.4 to 15.6 V, and secondary supply voltages are monitored with defined power-good thresholds. Coupling capacitance is 16 to 20 pF. Partial discharge voltage supports up to 7 kV. The driver uses a separate gate interface card and requires >30 mm creepage between primary and secondary sides. It is compatible with the T1680TC17G IGBT.
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 .
