  • Publication number: 20190279832
    Abstract: A power supply control device controls the supply of power via a switch circuit and a relay contact. If the semiconductor switches are on and the relay contact is off, when a switch temperature of the switch circuit is at least a relay ON-threshold, the relay contact is switched on, and the semiconductor switches are switched off. If the semiconductor switches are off and the relay contact is on, when a switch temperature of the switch circuit is lower than a relay OFF-threshold, the semiconductor switches are switched on, and the relay contact is switched off. The relay OFF-threshold is not more than the relay ON-threshold.

  • Publication number: 20190267795
    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.

  • Publication number: 20190260338
    Abstract: A power supply control device controls power supply via a switch by causing a drive circuit to turn on and off the switch. A first resistance is disposed on a path of a current flowing via the switch. A differential amplifier outputs a voltage corresponding to a value of a voltage between two ends of the first resistance. A first capacitor is connected between a point midway on a path of power supply to the differential amplifier and an upstream end of the first resistance. A second capacitor is connected between a point midway on the path of power supply and a downstream end of the first resistance.

  • Publication number: 20190258284
    Abstract: A power supply control device includes a switch disposed in a first current path of a current flowing from a battery. A first comparator compares a voltage value of a current input end of the switch to which the current is inputted with a voltage threshold. When the voltage value of the current input end is less than the voltage threshold, a drive circuit turns off the switch. The battery supplies, via a second current path, power to a starter that starts an engine of a vehicle. The voltage threshold is less than the voltage value of the current input end of the switch in the case where the battery supplies the power to the starter.

  • Publication number: 20180358800
    Abstract: A control circuit turns ON or OFF a switch that is provided at a midpoint of a wire. Thus, power supply via the wire is controlled. A current output circuit outputs a current that corresponds to a current flowing through the wire to a resistance circuit. In the resistance circuit, a series circuit of a resistor (R2) and a capacitor (C1) is connected in parallel to a resistor (R1). The control circuit) turns OFF the switch if the end-to-end voltage value of a voltage across both ends of the resistance circuit is larger than or equal to a reference voltage value.

  • Publication number: 20180358806
    Abstract: In a power supply control apparatus, a control circuit adjusts a resistance between a drain and a source of a semiconductor transistor by adjusting the voltage at a gate of the semiconductor transistor. After the control circuit has lowered the resistance between the drain and the source, a control portion determines whether or not the voltage at the source detected by a voltage detecting portion is larger than or equal to a standard voltage. If the voltage at the source is larger than or equal to the standard voltage, the control circuit again lowers the resistance between the drain and the source. If the voltage at the source is smaller than the standard voltage, the control circuit adjusts the resistance between the drain and the source to a resistance at the time when determination was performed or larger.

  • Publication number: 20180331556
    Abstract: In a power supply control apparatus, if a switching signal input from a microcomputer to a control circuit instructs switching on of a semiconductor switch, when an input voltage that is input to the drain of the semiconductor switch is higher than or equal to a predetermined voltage, the control circuit drives a charging circuit. The charging circuit charges a capacitor (Cs) via a diode (D1). Accordingly, a voltage at the gate of the semiconductor switch taking a potential at the source of the semiconductor switch as a reference becomes higher than or equal to a predetermined voltage, and thus the semiconductor switch is switched on. While driving the charging circuit, the control circuit keeps driving the charging circuit even if the input voltage becomes lower than the predetermined voltage.
