Abstract
A current detecting device of the invention has a temperature compensating function used for a current limiting device. A sensing resistance and a reference voltage source are connected to a comparison device. A compensating device, such as semiconductor element, is inserted in series into the reference voltage source in a voltage source circuit for supplying a reference voltage to compensate a temperature dependency of the sensing resistance. Temperature dependency of the reference voltage is a negative temperature dependency in the forward voltage drop. The manufacturing process of the current detecting device becomes simple.
