1. A device comprising:

  • a driver integrated circuit (IC) comprising a first control unit and a second control unit;

    a first solenoid that is electrically coupled to the first control unit;

    a second solenoid that is electrically coupled to the second control unit;

    at least one sensor;

    a clock that synchronizes a microcontroller and the driver IC; and

    a peripheral bus that communicatively couples the first control unit and the second control unit;

    wherein the microcontroller and the driver IC form an outer control loop configured to generate a control signal that controls actuation the first solenoid and the second solenoid; and

    wherein the first control unit, the second control unit, and the at least one sensor form an inner control loop configured to generate, based upon the control signal, an actuation signal that actuates the first solenoid and the second solenoid.
