Abstract
An output terminal of a signal output device is connected through a branch path to a voltage dividing point in a main path, and transmits an output signal based on a voltage of the voltage dividing point to an outside. A signal generation circuit adjusts the voltage of the voltage dividing point and generates the output signal. A short circuit detection circuit detects a short circuit between the output terminal and another terminal when a current flowing in the branch path is greater than a predetermined short circuit detection threshold. A switching circuit switches a current carrying capacity or a configuration of the signal generation circuit to limit a short circuit current flowing in the branch path when the short circuit is detected. The short circuit current is set to a value equal to or greater than the short circuit detection threshold and less than a current upper limit value.
