ABSTRACT:
A motor drive circuit includes a switching circuit having an input node that receives a drive signal and a control node that receives a control signal. The switching circuit couples the input node to an output node responsive to the control signal. A bias element receives an input signal and is coupled to the output node of the switching circuit. The bias element automatically develops a bias voltage on the output responsive to the input signal. The drive circuit may be used, for example, in a motor control system to control the speed of a DC motor, such as in a power supply for a computer system.
