Figure 10: Fast demag waveforms

The demagnetization of inductive load causes a huge electrical and thermal stress to the

IC. The curve plotted below shows the maximum demagnetization energy that the IC can

demagnetization energy is required then an external free-wheeling Schottky diode has to

be connected between OUT (cathode) and GND (anode) pins. Note that in this case the

fast demagnetization is inhibited.
