Abstract
In a fault detection protecting circuit, an overheat detection unit is provided for each of communication channels on an IC chip, and detects the temperature in each communication channel as the detected temperature. A chip temperature detection unit detects the temperature at an arbitrary position on the IC chip as a reference temperature. A detection unit sets a predetermined ratio value regarding the difference between an overheat protective temperature and a reference temperature based on the detected temperature in each communication channel and the reference temperature, and identifies that the communication channel is in a state before overheat detection when the detected temperature exceeds a threshold value. A stop-control unit stops the output from one of the communication channels when the detection unit identifies that the communication channel is in a state before overheat detection and when it is identified that the communication channel is in an overcurrent state.
