摘要： Disclosed is a power supply monitoring circuit including: a first terminal to which a first voltage as a highest voltage of a battery including cells is connected; a second terminal to which a second voltage as a lowest voltage of the battery is connected; a selection circuit that selects a high potential and a low potential of a cell; an analog-to-digital conversion circuit to which the high and low potentials are input; a power supply circuit that generates an operating voltage of the analog-to-digital conversion circuit; and a logic circuit that receives a signal from the analog-to-digital conversion circuit, processes the signal, and outputs a signal from a third terminal to an external device. The operating voltage is a first operating voltage with a midpoint of the high potential and the low potential as a reference.

摘要： A semiconductor integrated circuit device includes the following. An output transistor is connected between a voltage input terminal and a voltage output terminal. A control circuit controls an on state or an off state of the output transistor. An overcurrent detection circuit is capable of detecting a current that is a predetermined value or more flowing in the output transistor. A retry circuit generates and outputs a signal to intermittently switch the output transistor to the off state according to the overcurrent detection circuit detecting an overcurrent state. An external terminal outputs an error flag signal showing an abnormality. The control circuit repeats control to temporarily turn off the output transistor. After the overcurrent detection circuit detects the overcurrent state, the retry circuit is configured so that the error flag signal continuously shows an abnormality while the control circuit repeats control to temporarily turn off the output transistor.

摘要： A first device: determines whether or not a terminal voltage at a terminal, where a temperature sensor, in which a physical quantity such as a resistance value or a voltage value varies due to changes in temperature, is connected, is in a first voltage range; controls the terminal voltage to vary in accordance with changes of the physical quantity, within the first voltage range, when the terminal voltage is determined to be in the first voltage range, and stops controlling the terminal voltage to vary within the first voltage range when the terminal voltage is determined not to be in the first voltage range; and detects temperature based on the terminal voltage. A second device: controls the terminal voltage to vary in accordance with changes of the physical quantity, within a second voltage range, which is different from the first voltage range; and detects temperature based on the terminal voltage.

摘要： A push switch contains a circuit substrate, two fixed contacts disposed on the circuit substrate, a dome-shaped spring which is disposed above the two fixed contacts and can be displaced between a first position in which the two fixed contacts are in a non-conductive state and a second position in which the two fixed contacts are in a conductive state and a conductive elastic member disposed on a surface of the dome-shaped spring facing the circuit substrate and having a surface facing the two fixed contacts. At least the surface of the conductive elastic member facing the two fixed contacts has conductivity. When the dome-shaped spring is displaced to the second position, the two fixed contacts are in the conductive state through the conductive elastic member.
