Maximum Load Inductance
While demagnetization of inductive loads, energy has to be dissipated in the
BTS 5234G. This energy can be calculated with following equation:
Following equation simplifies under the assumption of
The energy, which is converted into heat, is limited by the thermal design of the
component. See
