摘要
A power processing circuit operatively and electrically connected to one regulated supply (16) voltage responds through a comparator means (24) and a monitor means (26) to generate a reset pulse (84) to a microprocessor (28) whenever the regulated supply voltage starts to go out of regulation. The comparator means functions both as a control circuit to maintain regulation as well as a comparator to determine when the base current of the pass transistor (52) begins to saturate the pass transistor. The monitor means (26) responding to this condition generates a minimum time length reset pulse to the microprocessor.
