Abstract
Provided are a magnetic sensor, which is capable of accurately determining abnormalities, such as disconnection and a short circuit, of wiring of a magnetic sensor device, and the magnetic sensor device. An output control circuit of the magnetic sensor includes a voltage divider circuit, which is connected to an output terminal of the magnetic sensor, and an amplifier, which is configured to control a gate voltage of a MOS transistor, which is connected to the output terminal of the magnetic sensor, so that a voltage of the voltage divider circuit and a reference voltage become equal to each other, with the result that an output voltage of the magnetic sensor is determined by the reference voltage and a voltage dividing ratio of the voltage divider circuit.
