Abstract
A short-circuit determination circuit includes a current detection unit, a voltage detection unit, and a short-circuit determination unit. The current detection unit detects the current flowing in a power circuit. The voltage detection unit detects the voltage applied to the power circuit. The short-circuit determination unit determines a short circuit in the power circuit on the basis of the difference between a detection value of the current detected by the current detection unit and a detection value of the voltage detected by the voltage detection unit.
Claims5
A short-circuit determination circuit comprising:
- a current detection unit that detects current flowing in a power circuit and outputs a first value that represents a detected current flowing in the power circuit;
- a voltage detection unit that detects voltage applied to the power circuit and outputs a second value that represents a detected voltage applied to the power circuit;
- and
- a short-circuit determination unit that determines a short circuit in the power circuit based on a difference between the first value and the second value.
