ABSTRACT:
A power source voltage change discrimination circuit includes a voltage selection circuit for selectively supplying the greater one of main and auxiliary power source voltages, and a series circuit of a resistor and a capacitor coupled between the output terminal of the voltage selection circuit and ground. There is further provided a Schmitt circuit having hysteresis characteristics whose input terminal is coupled to a junction of the resistor and capacitor.
