... APPLICATION INFORMATION When inductive loads are driven by L6221A/N, a zener diode in series with the integral free-wheeling diodes increases the voltage across which energy stored in the load is discharged and therefore speeds the current decay (fig. 18). For reliability it is suggestedthat the zener is chosen so that < ...
