  • Patent number: 7262571
    Abstract: A braking module includes a braking load, an input terminal, an output terminal, and control logic. The input terminal is adapted to receive a motor drive signal. The control logic is adapted to receive a motor enable signal, couple the output terminal to the input terminal responsive to the motor enable signal being asserted, couple the output terminal to the braking load responsive to the motor enable signal being deasserted, and prevent the coupling of the output terminal to the input terminal responsive to a temperature of the braking module exceeding a predetermined disable set point. A method for controlling a motor includes coupling a drive lead carrying a motor drive signal to a motor lead of the motor responsive to a motor enable signal being asserted. The motor lead is coupled to a braking load responsive to the motor enable signal being deasserted.
