Figure 11. Typical application circuit
Motor selection
Some stepper motor have such high core losses that they are not suitable for switch mode
current regulation. Furthermore, some stepper motors are not designed for continuous
operating at maximum current. Since the circuit can drive a constant current through the
motor, its temperature might exceed, both at low and high speed operation.
Unused inputs
Unused inputs should be connected to the proper voltage levels in order to get the highest
noise immunity.
