Advance Product Bulletin Diamond Power Products BG2B-Universal Dual IGBT Module Gate Driver Board Free Sample Board with purchase of Gate Driver and DC-DC Converter Description Features BG2B is a fully isolated gate drive circuit board designed for use with dual IGBT modules. When the board is populated, gate drive is supplied by M57159L, M57959L, M57962L or M57160AL hybrid gate drivers to provide efficient switching of modules rated up to 400A. The hybrid gate drivers also provide protection against unexpected short circuit conditions. Isolated control power for the driver is supplied by a pair of onboard M57145L-01 regulated DC/DC converters. The fault feedback signals are also optically isolated.
