Demagnetization of inductive loads
An internal zener diode, limiting the voltage across the Power MOS to between 50 and 60 V
(Vcl), provides safe and fast demagnetization of inductive loads without external clamping
devices. The maximum energy that can be absorbed from an inductive load is specified as
200 mJ (at T
