Abstract: An apparatus for controlling a stepper motor comprises a driver circuit and a brake circuit each having a motor controller device. The driver circuit, brake circuit and motor are connected in parallel. The driver circuit receives an enabling signal and outputs driver current to the motor accordingly. The brake circuit includes a logic circuit which receives the enabling signal, a brake input signal, and a power supply status signal, and outputs a brake logic signal. The brake circuit motor controller device is coupled to the logic circuit. This motor controller device receives an output of the brake logic circuit and outputs braking current to the motor in accordance therewith. The braking circuit is effective to prevent movement of the motor shaft in accordance with output of the braking current. The motor controller devices are substantially identical. The apparatus is effective to control the motor while avoiding generation of RF noise.
