Abstract
A circuit configuration serves to regulate in particular a coil current for a hydraulic pressure regulating valve of a motor vehicle transmission. A current measuring resistor configured as a thick-film resistor and a temperature sensor, that detects a transmission oil temperature and is thermally coupled to the current measuring resistor, are applied on a circuit carrier produced from a ceramic material. The signals of the current measuring resistor and of the temperature sensor are fed to a control unit, in which the signal of the temperature sensor is used to compensate for a temperature-dependent resistance of the current measuring resistor.
