Introduction
An automobile is an unforgiving environment for integrated circuits, where under-the-hood operating temperatures run from −40°C to 125°C and large transient excursions on the battery voltage bus are expected. In the past, electronics were part of the well-protected and centralized Engine Control Unit (ECU), but the trend is toward more distributed electronics. Electrically driven accessories and fault-protection monitoring ...
