The C0044BG400SBG is an IGBT gate driver designed for press-pack IGBTs, featuring a fiber-optic interface for switching commands and status feedback, integrated DC/DC converter with soft start, and EMI filtering. It delivers a peak gate current of 44 A, with gate-on and gate-off voltages of +15 V and -15 V, respectively. The driver includes VCE-desat detection with a trip level of 25 V, soft turn-off timing of 30 μs, and monitoring of all secondary supply voltages. It operates with a primary supply voltage of 15 V and maintains a propagation delay of 1.4 μs. The device is mounted with a separate gate interface card and meets a partial discharge voltage of at least 2.5 kV, with creepage distances exceeding 30 mm on the PCB. The case and mounting style are defined by the separate interface card configuration. The driver complies with high-reliability standards for industrial use.
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 .
