Abstract: An electronic unit includes a heat sink, a substrate, a heating component, a temperature sensor, a first interconnection, and a second interconnection. The heat sink includes a strut. The substrate is fixed to the strut of the heat sink. The heating component is mounted on the substrate to generate heat upon energization of the heating component. The temperature sensor is mounted on the substrate to detect temperature. The first interconnection is provided in a high-temperature region in which the heating component is mounted on the substrate, and is connected to the strut of the heat sink. The second interconnection is provided in a detection region in which the temperature sensor is mounted on the substrate, and is provided separately from the first interconnection. The second interconnection is connected to the strut of the heat sink and the temperature sensor.

Abstract: A motor controller includes, in a microcomputer, a voltage fall determiner determining whether a reference voltage falls from a normal value based on an Analog-to-Digital (A/D) conversion value of a second voltage from an A/D converter, and a corrector (i) calculating a correction coefficient based on the A/D conversion value of the second voltage from the A/D converter and (ii) correcting an A/D conversion value of an input voltage that is output from the A/D converter. A core of the microcomputer generates a control signal based on an input voltage A/D conversion value, when the voltage fall determiner determines that the reference voltage is equal to or higher than a normal reference value. The motor controller keeps its motor control accuracy in such manner, even when a fall of an A/D conversion reference voltage is observed.

Abstract: A power source system provides: an electrical generator including a rectifying circuit configured by one or more rectifying diodes for allowing electric conduction from a ground side to a battery side; a fuse arranged between the electrical generator and a battery; and a driving apparatus including a circuit configured by one or more semiconductor elements having one or more parasitic diodes for allowing electrical conduction from the ground side to the battery side, and a load. The number of parasitic diodes to be connected in series between a ground and the fuse in the driving apparatus is larger than the number of rectifying diodes to be connected in series between the ground and the battery side in the electrical generator. In addition, the circuit switches electrical conduction in the load.

Abstract: A motor controller includes, in a microcomputer, a voltage fall determiner determining whether a reference voltage falls from a normal value based on an Analog-to-Digital (A/D) conversion value of a second voltage from an A/D converter, and a corrector (i) calculating a correction coefficient based on the A/D conversion value of the second voltage from the A/D converter and (ii) correcting an A/D conversion value of an input voltage that is output from the A/D converter. A core of the microcomputer generates a control signal based on an input voltage A/D conversion value, when the voltage fall determiner determines that the reference voltage is equal to or higher than a normal reference value. The motor controller keeps its motor control accuracy in such manner, even when a fall of an A/D conversion reference voltage is observed.
