  • Integrated circuit arrangement for current regulation
    Patent number: 7840365
    Abstract: An integrated circuit arrangement for current regulation of an electromagnetic load, especially an electric motor, generator, solenoid valve, or the like, with a coil, a power switch element, and a freewheeling diode is disclosed. In one embodiment, the circuit arrangement has an integrated measurement resistor for measuring the coil current. The measurement resistor is arranged in a freewheeling path of the circuit arrangement in series between the freewheeling diode and the power switch element, and has a digital processing means connected after a voltage measurement device assigned to the measurement resistor for at least partial compensation of resistor manufacturing variations and/or temperature fluctuations in the voltage signal and/or an error due to analog voltage signal processing.
