ABSTRACT:
This relates to a monolithically integrable circuit for providing an effective constant voltage to automobile instruments; fuel, temperature, etc. The standard bi-metallic switch is replaced by a power amplifier which is turned on and off by a Schmidt trigger circuit. A capacitor charge/discharge circuit is charged by a current source, the output of which varies with output voltage. When the switch level of the Schmidt trigger is reached, the power amplifier is turned off and the output grounded via the instruments. This turns off the charging source and turns on a discharging source. In this manner, the on/off ratio of the output is varied to supply an effective constant voltage to the instruments.
