Title:
給電制御装置
Document Type and Number:
Japanese Patent JP6610446
Kind Code:
B2
Abstract:
A power supply control apparatus controls power supply via a semiconductor switch, by a driving circuit turning ON or OFF the semiconductor switch. A current circuit pulls in a current from the drain of the semiconductor switch via a resistance. The current value Ic of the current that is pulled in by the current circuit fluctuates in the same direction as a fluctuation direction of the ON resistance value of the semiconductor switch, depending on the ambient temperature of the semiconductor switch. If the source voltage of the semiconductor switch is lower than a voltage at the other end of the resistance, the driving circuit turns OFF the semiconductor switch.
