  • Circuitry and method for regulating a current for diagnosing an electromechanical load utilizing multiple current measurements
    Patent number: 9698678
    Abstract: A circuitry for regulating a current for an electromechanical load comprises a first connection and a second connection for the electromechanical load. The first connection can be coupled to a first supply potential thereby, and a potential of the second connection can be modified by means of a pulse width modulation. The circuitry also comprises a measurement assembly having a first measurement signal input, which is coupled to the first connection and a second measurement signal input, which is coupled to the second connection. The measurement assembly is designed thereby to determine a measurement signal that is proportional to a potential difference between the first and second connection, in order to regulate the current for the electromechanical load on the basis of the measurement signal.
