Filed: 1991-12-21
Abstract: PURPOSE: To effectively short-circuit an electronic switch by providing a protection circuit which judges a load time, when a current can exceed a threshold corresponding to a reference value without being triggered, to be reasonable to allow it. CONSTITUTION: When an excessive current flows to an electronic switch S, a parameter voltage VRN immediately exceeds a reference value U0 , and the output of a comparator CMP0 goes to the high level to turn in an electronic switch S1 , and a capacitor C is charged by a constant current source G1 . When a terminal voltage VC is increased then to exceeds a threshold U1 , a reset input terminal RESET of a bistable circuit goes to L. At this time, an output QF is kept in the same level, and the switch S1 is kept turned on, and the voltage VC continues to increase because the capacitor C continues to be charged. When the voltage VC exceeds a threshold U1 +U2 , a set input SET is switched to '1', and then, the output QF is switched to '0'. As the result, a voltage is eliminated from the base of the switch S, and the switch is not made conductive.
