Demagnetization of inductive loads
The device has four internal clamping diodes able to demagnetize inductive loads.
The limitation is the peak power dissipation of the packages, so — if the loads are big or if
there is the possibility to demagnetize more loads contemporarly — it is necessary to use
external demagnetization circuits.
