Abstract
A battery voltage level detecting apparatus makes possible the detection of the voltage level of a battery and the detection of a minimum operating voltage by means of a single comparison circuit and a single adjustment. A voltage varying with variation of the battery voltage is compared with an output voltage of a counter for counting reference clocks so as to control the counting operation. When a change occurs in the comparison result, a battery voltage level storage command is generated, and then the counter is preset. In response to the command, the count value is stored and displayed.
