摘要：A circuit arrangement for automatic, load-dependent control of at least one
winding current of a respective motor winding of a self-timed bipolar stepper motor,includes a first power driver circuit for a first motor winding and a second power drivercircuit for a second motor winding. The circuit arrangement includes a first XOR gate anda second XOR gate, and a first resistor connected so as to couple the first XOR gate to ananode of a first diode. A cathode of the first diode is coupled to the comparator input ofthe first power driver circuit via a second resistor. A third resistor is connected so as tocouple the second XOR gate to an anode of a second diode. A cathode of the seconddiode is coupled to the current-controlling comparator input of the second power drivercircuit via a fourth resistor.
