The C0044BG400 is an IGBT gate driver designed for high-reliability applications, featuring fiber-optic links for command and feedback, a built-in DC/DC converter with soft start, and integrated EMI filtering. It delivers a peak gate current of 44 A and supports partial discharge voltages up to 7 kV. The driver monitors secondary supply voltages and IGBT switching status via Vce-desat detection, with a configurable trip level of 25 V and a soft switch-off time of 30 µs. Propagation delay is typically 1.4 µs, and the device operates within a temperature range of -20 °C to +55 °C. It uses a separate gate interface card for optimal IGBT coupling and has a primary-to-secondary
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 .
