a voltage level detecting circuit includes a resistance voltage divider , a level converter and an mos driver arranged such that the detection characteristics are immune to temperature variations . the voltage divider has two resistive elements serially connected to each other to produce a divided voltage . the two resistive elements have different resistance variations to temperature change . the level converter has a threshold voltage and converts a divided voltage which is more than the threshold voltage from the voltage divider into a binary signal . the mos driver produces a control signal on receipt of a binary signal from the level converter .
