  • Optimal fan presence detection
    Publication number: 20060181231
    Abstract: Detecting the presence of an electric fan is described. A current sink circuit is coupled to a pulse width drive output of a fan control circuit. A logic state in a logic input buffer is defined based on current flow through the current sink. The logic state indicates if a fan is coupled to the pulse width drive output.

  • Method and apparatus for driving a brushless DC motor
    Publication number: 20050258789
    Abstract: A drive circuit for a brushless DC motor includes a switch constructed and arranged to drive the motor with a pulse signal responsive to a control signal, and control circuitry coupled to the switch and constructed and arranged to generate the control signal responsive to rotor position information from the motor so as to synchronize the pulse signal to the rotor position. A current sensing device can be used to provide the rotor position information to the control circuitry by sensing current flowing through the motor.
