Abstract
A protection circuit is disclosed for use in automotive or industrial high power integrated circuits equipped with reverse battery protection and reverse current protection. The protection circuit prevents formation of parasitic devices that could cause the high power integrated circuit to malfunction or fail to turn on. The protection circuit features asynchronous operation of a pair of MOSFETs coupled between a power supply and a load. The protection circuit can be engaged at start-up or in response to transient conditions associated with a fault.
