APPLICATION INFORMATION
When inductive loads are driven by L6220/N, a
zener diodein series with theintegralfree-wheeling
diodes increases the voltage across which energy
stored in the load is discharged and therefore
speedsthe current decay(Fig. 16). For reliability it
is suggested that the zener is chosenso that V
p
+
V
z
< 35 V.
The reasons for this are two fold :
1) The zenervoltage changesin temperature and
current.
2) The instantaneouspower must be limited to
avoid thereverse secondbreakdown.
