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. At nominal battery voltage the output is clamped to V
the output is clamped to V

Maximum Load Inductance
While de-energizing inductive loads, energy has to be dissipated in the BTS50080-1EGA. This energy can be
calculated by the following equation:
In the event of de-energizing very low ohmic inductances ( R
The energy, which is converted into heat, is limited by the thermal design of the component. See
