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

IC. The curve plotted in Figure 12 shows the maximum demagnetization energy that the IC

can support in a single demagnetization pulse with VCC = 24 V and TAMB = 125 °C. If higher

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.
