ABSTRACT:
A power transition circuit protects a bipolar-CMOS (BiCMOS) circuit during power transitions. Reference signals proportional to the voltage supplied to the protected circuit are monitored, and the power transition circuit determines from the voltage differential between the reference signals whether a power transition is occurring. If a transition is present, the transition circuit disables the protected BiCMOS circuit for as long as the power transition exists. An independent input signal allows the power transition circuit to disable the protected BiCMOS circuit in response to other conditions.
