MOTOR SELECTION
Some stepper motors are not designed for continu-
ous operation at maximum current. As the circuit
drives a constant current through the motor, its tem-
perature might increase exceedingly both at low and
high speed operation.
Also, some stepper motors have such high core
losses that they are not suited for switch mode cur-
rent regulation.
UNUSED INPUTS
Unused inputs should be connected to proper voltage
levels in order to get the highest noise immunity.
INTERFERENCE
As the circuit operates with switch mode current
regulation, interference generation problems might
arise in some applications. A good measure might
then be to decouple the circuit with a 15 nF ceramic
capacitor, located near the package between power
line VS and ground.
The ground lead between RS, CC and circuit GND
should be kept as short as possible. This applies
also to the lead between the sensing resistor RS and
point S, see FUNCTIONAL BLOCKS.
