<p>A temperature detecting apparatus includes an integrated circuit that integrates an overheating detecting circuit, a breakage detecting circuit and a disabling circuit, and an element connection terminal connecting a temperature sensing element. The disabling circuit disables the breakage detecting circuit from detecting a breakage of wire when a voltage at the element connection exceeds a disabling threshold which is set higher than an overheating detection threshold and a breakage detection threshold. A predetermined voltage higher than the disabling threshold is applied to the element connection terminal when the temperature sensing element is not connected to the element connection terminal.</p> |
