5.3.2
During demagnetization of inductive loads, energy has to be dissipated in the BTS5045-1EJA. 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
maximum allowed energy dissipation as a function of the load current.

In case of inverse current, meaning a voltage
will flow from output to
stage follows the state of the IN pin, except if the IN pin goes from OFF to ON during inverse. In that particular
case, the output stage is kept OFF until the inverse current disappears. If the channel is OFF, the diagnostic will
detect an open load at OFF. If the channel is ON, the diagnostic will detect open load at ON (the overtemperature
signal is inhibited). At the appearance of
and reflects the output state. At
current, no protection functions are available.
