Applications

* where a complex microprocessor is unavailable or is overburdened. The chopping control in the A3982 automatically selects the current decay mode (Slow or Mixed). When a signal occurs at the STEP input pin, the A3982 determines if that step results in a higher or lower current in each of the motor ph
