2-Phase Stepper-Motor Driver

Siemens AG 

TCA 3727

The direction and value of current are programmed for each phase via separate control

inputs. A common oscillator generates the timing for the current control and turn-on with

phase offset of the two output stages. The two output stages in a full-bridge configuration

have integrated, fast free-wheeling diodes and are free of crossover current. The logic is

supplied either separately with 5 V or taken from the motor supply voltage by way of a

series resistor and an integrated Z-diode. The device can be driven directly by a

microprocessor with the possibility of all modes from full step through half step to mini

step.
