A New Half-Bridge High Voltage Monolithic IGBT Gate Driver with Full Protection and Diagnostic Feedback
نویسندگان
چکیده
A new half bridge gate driver IC for high voltage applications developed in high-voltage CMOS technology is described. It includes two driving stages able to source and sink 2A and 3A respectively: one driver is referenced to ground voltage, while the other may float up to 1200V above the former. The IC integrates the full digital section to interface a 3.3V controller and includes a set of features to protect the IGBT in case of undervoltage at main supply or short circuit at the output managing multi-phase systems and to prevent shoot-through events. Diagnostic information is provided through I/O pin.
