Abstract
Disclosed herein is a single integrated circuit chip with a main logic that operates a vehicle component such as a valve driver. Isolated from the main logic within the chip is a safety area that operates to verify proper operation of the main logic. The safety area is internally powered by an internal regulated voltage generated by an internal voltage regulator that generates the internal regulated voltage from an external voltage while protecting against shorts of the external line delivering the external voltage. The safety area includes protection circuits that level shift external analog signals downward in voltage for monitoring within the safety area, the protection circuits serving to protect against shorts of the external line delivering the external analog signals.
