When switching off inductive loads, the output voltage
inductance ( -d

To prevent destruction of the device, there is a voltage clamp mechanism implemented that keeps the voltage drop
across the device at a certain level (
inductance is limited.

While de-energizing inductive loads, energy has to be dissipated in the BTS5016SDA. This energy can be
calculated via the following equation:
In the event of de-energizing very low ohmic inductances (
