IGBT driver IC including advanced control and protection functions
IGBT devices play a large role in power applications due to their high current/voltage capability and ease
of driving. The majority of industrial applications use a 3-phase inverter with 1200V IGBT. Driving these
devices in medium or large power applications requires separate, floating high- and low-side drivers with
galvanic insulation. Control and protection functions are also required to ensure reliable operation. The
device presented hereafter is a new integrated circuit that includes all the functions necessary to directly
drive an IGBT in power applications and is especially adapted to 1200V IGBT with current ratings of 25 to
80A in Econopak-like modules.
