    摘要: An output circuit has a smaller area and restrains outputs from becoming unstable even if a power supply voltage is lower than an operating voltage. A supply terminal of an inverter circuit is provided with switch circuit, and the switch circuit stops the operation of the inverter circuit when the power supply voltage is lower than the operating voltage of the circuit. Further, the output terminal of the inverter circuit is provided with a current source to fix the output to the power supply voltage when the operation of the inverter circuit is stopped.

    摘要: Provided is a detection circuit for monitoring a power supply voltage with a circuit configuration in which power consumption is reduced, and a sensor device including the detection circuit. A detection circuit (100) detects an input signal input thereto to output an output signal. An interrupt condition generating circuit (10a) directly detects a power supply voltage (VDD) supplied thereto from a power supply, and outputs an interrupt signal until the power supply voltage makes a transition to a predetermined voltage range. An interrupt condition reception circuit outputs, as an output signal, a given voltage without allowing an input signal (Vtemp) to be output until an interrupt caused by the interrupt signal is released, and outputs, as an output signal, the input signal by allowing the input signal to be output when the interrupt caused by the interrupt signal is released.
