Title:
WIRE PROTECTION DEVICE, WIRE PROTECTION METHOD, AND COMPUTER PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/251118
Kind Code:
A1
Abstract:
In a power supply control device (10) that functions as a wire protection device, a fusion element (F1) is disposed on a current pathway for current that flows through a wire (W1). The fusion element (F1) fuses according to the temperature of the fusion element (F1). A switch circuit (G1) has an FET. The FET is disposed on the current pathway for the current that flows through the wire (W1). The FET is switched off when a microcomputer (20) has determined that the wire temperature of the wire (W1) is greater than or equal to a temperature threshold.
