Abstract: A power supply control device is to be installed in a vehicle. The power supply control device controls power supply via a semiconductor switch and a fuse by turning the semiconductor switch ON or OFF. The semiconductor switch and the fuse are mounted on a circuit board. In the fuse, two long plate-shaped terminals are arranged in a row. The fusing portion and a part of the two terminals are covered with a housing having heat resistance. The two terminals are disposed in a current path of a current flowing through the semiconductor switch. The current flows through the fusing portion. If the temperature of the fusing portion exceeds a predetermined temperature, the fusing portion is fused.

Abstract: A power supply control apparatus controls power supply from a DC power source to a load by switching on or off a power supply FET. The current adjustment circuit adjusts the current flowing through the resistor circuit to a value obtained by dividing the voltage between the drain and the source of the power supply FET by the resistance value of the resistor circuit. A drive circuit switches off the power supply FET when a voltage across the detection resistor exceeds a predetermined voltage. The on-resistance value of the power supply FET fluctuates according on the ambient temperature of the power supply FET. The resistance value of the resistor circuit fluctuates in the same direction as the on-resistance value according to the ambient temperature of the power supply FET.

Abstract: In a vehicle-mounted system, a first ECU (or “first vehicle-mounted device”) and a second ECU (or “second vehicle-mounted device”) are connected to a communication bus. When the first ECU has received the first or second activation data via the communication bus in a low-power state where power consumption is low, the first ECU transitions to a high power state whose power consumption is larger than the low power state. When the second ECU has received the first data via the communication bus in a low-power state where power consumption is low, the second vehicle-mounted device is maintained in the low power state. When the second ECU has received the second data via the communication bus in the low-power state, the second ECU transitions to a high power state. A management device transmits the first activation data and the second activation data via the communication bus.
