ABSTRACT:
An automotive battery charging system includes a novel temperature compensation arrangement. The conventional input potential divider has a further resistor and a temperature compensation output transistor in series across one leg of the divider. The voltage at the base of the temperature compensation output transistor is controlled by a temperature sensing circuit so as to fall linearly with rising temperature. Resistors are adjusted in manufacture to give the required level and slope for the temperature compensation characteristic.
