Electronic circuit arrangement for vehicle, has voltage comparator circuit comparing signal voltage with reference voltage, and correction circuit correcting voltage drop in accordance with change of consumption stream of processor circuit

摘要

The arrangement (10) has a signal processor circuit subjecting an input signal (Sig1) to a specific signal processing in an input terminal (IN1). A voltage comparator circuit (14) compares a signal voltage of another input signal (Sig2), which is applied separately from the former input signal to another input terminal (IN2), with a predetermined reference voltage. A correction circuit corrects voltage drop of current limiting resistance in accordance with a change of consumption stream of the signal processor circuit to invariably maintain a threshold value voltage.
