Abstract

A control system includes: a semiconductor chip, having built therein a processing part, an A/D converter and a pull device circuit; a wiring part, having one end connected to a terminal connected to the A/D converter; and a sensor, connected to the other end of the wiring part and inputting a sensor signal in analog form via the wiring part. The pull device circuit includes a switching element, and has one end connected to ground or a power supply voltage and the other end connected between the A/D converter and the terminal. The processing part includes: a switch control part, controlling the switching element to be in an on or off state; a sensor information generator, generating sensor information based on the sensor signal; and a disconnection detector, detecting disconnection of the wiring part based on output of the A/D converter when the switching element is in the on state.
