Application informations
Some stepper motors are not designed for contin-uous operation at maximum current. As
the circuit drives a constant current through the motor, its temperature 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 current regulation.
Unused inputs should be connected to proper voltage levels in order to get the highest noise
immunity. 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 100 nF capacitor, located near the package between power line
and ground. The ground lead between Rs, and circuit GND should be kept as short as
possible. A typical application circuit is shown in
similar else. To sense the winding current, paralleled metal film resistors are recommended
(R
