ABSTRACT:
An active deassertion circuit is a device that prevents signal lines used with a communications protocol from drawing too much current. Thus, the device prevents the driver(s) of the signal lines from malfunctioning and/or being damaged. The active deassertion circuit is comprised of a voltage regulator, with peripheral connections, coupled to a transistor that is used to sink excess current. The function of these elements ensures that no asserted signal line draws too much current if another signal line is actively deasserted. A method of using the active deassertion circuit is also disclosed.
