A Smartmos™ Integrated Circuit for Diagnostic Testing

A SMARTMOS^™ power integrated circuit has been developed for diagnostic testing in vehicles. The SMARTMOS^™ process is ideal for this application because of its robustness to temperature and voltage extremes. The IC serves as an interface between logic level microcontrollers and battery level testers. It is fully compatible with the ISO 9141 requirement for the interchange of digital information in vehicle diagnostic systems.
