Abstract:
A hot sensor detects a temperature of an output transistor and a cold sensor detects a temperature of a position distant from the output transistor. When the temperature of the hot sensor rises more than a reference temperature, a temperature detecting circuit asserts an overtemperature detecting signal, and when a temperature difference between the hot sensor and the cold sensor is more than a reference temperature difference, the above circuit asserts the temperature difference detecting signal. A current limiting circuit generates a limited current signal sequentially variable with the negative temperature characteristic for the temperature of the cold sensor and controls a drive current of the output transistor to a current value depending on the signal level of the limited current signal when the overtemperature detecting signal is asserted.

Claim (Index 2):
The device according to  claim 1 ,\n wherein after asserting the overtemperature detecting signal, the temperature detecting circuit negates the overtemperature detecting signal when the temperature of the hot sensor is reduced by a first hysteresis temperature, and after asserting the temperature difference detecting signal, the above circuit negates the temperature difference detecting signal when the temperature difference is reduced by a second hysteresis temperature, the above device further comprising: a logic circuit which controls on and off the output transistor to control the temperature of the hot sensor to the reference temperature, using the overtemperature detecting signal and controls on and off the output transistor to control the temperature difference to the reference temperature difference, using the temperature difference detecting signal, wherein the overtemperature detecting signal is asserted when the temperature of the cold sensor is higher than a boundary temperature, wherein the temperature difference detecting signal is asserted when the temperature of the cold sensor is lower than the boundary temperature, and wherein the limited current signal sequentially changes with the negative temperature characteristic for the temperature of the cold sensor in a temperature range in which the temperature of the cold sensor is higher than the boundary temperature.
