Abstract
A delay-on-break circuit adaptable for A.C. or D.C. applications utilizes a timer and a pair of comparators to prevent a load from being re-energized until at least a predetermined period of time has elapsed since the most recent deenergization of the load. A feedback element, such as a zener diode, connected between the output of one of the comparators and a feedback input thereof provides reliable latching of the load through zero crossings of the line in A.C. applications without use of a latching capacitor while simultaneously providing brownout protection capable of rapidly deenergizing the load in the event of an undesired decrease in line voltage.
