Abstract
A power supply control device controls power supply through a wire. A first current output circuit is configured to output, to a temperature difference circuit, a current that is larger the larger a wire current, which flows through the wire is. The temperature difference circuit is configured to output a voltage that is higher the larger a temperature difference between a wire temperature of the wire and an ambient temperature in the surroundings of the wire is. A drive circuit is configured to interrupt a flow of the wire current if the output voltage of the temperature difference circuit is at least a voltage threshold.
Claims8
A power supply control device for controlling power supply via a wire, comprising:
- a current output circuit configured to output a current that is larger the larger a wire current, which flows through the wire, is;
- a temperature difference circuit to which the current output by the current output circuit is input, and which is configured to output a voltage that is higher the larger a temperature difference between a wire temperature of the wire and an ambient temperature in the surroundings of the wire is;
- and
- an interruption unit configured to interrupt a flow of the wire current if the output voltage of the temperature difference circuit is at least a voltage threshold.
