An ignition IGBT with smart functions in chip on chip technology

A smart IGBT for automotive ignition applications is presented. In addition to the well-known advantages of an IGBT, e.g. low saturation voltage, this device uses the capabilities of integration to provide new functions such as current limitation, current flag and voltage feedback. This product is realized by using a chip on chip technology, allowing optimized technologies for the power and logic functions, respectively. Results of first samples are shown.
