... L6376 8 Short circuit operation In order to allow normal operation of the other inputs when one channel is in short cirtuit, an innovative non dissipative over current protection (patent pending) is implemented in the device. Figure 5. Short circuit operation waveforms OUTPUT CURRENT out DIAG (active low) In this way, the temperature of the device is kept enough low to prevent the intervention of the thermal protection (in most of the cases) and so to avoid the shut down of the whole device ...

... L6376 11 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 — necessary to use external demagnetization circuits. ...
