Maximum Load Inductance
While demagnization of inductive loads, energy has to be dissipated in the BTS 5231GS.
This energy can be calculated with following equation:
This equation simplifies under the assumption of
The energy, which is converted into heat, is limited by the thermal design of the
component. See
