ABSTRACT:
A current regulator is disclosed which utilizes a well known driver chip. The driver chip has an input signal known as a brake signal "BRK" which typically is used to stop a standard DC motor. In this invention, the brake signal "BRK" is used to create a low resistance current path in order to sustain the current of the current regulator which is used in conjunction with a stepper motor.
