Maximum Load Inductance
While de-energizing inductive loads, energy has to be dissipated in the BTS50080-1TEB. This energy can be
calculated via the following equation:
E = VON(CL) ⋅
V----b--b----–------V---O----N---(--C---L---)--
RL
⋅ ln1 +
--V---O---N---R-(-C-L--L--⋅-)--I--L–-----V---b---b
+ IL
⋅
--L---
RL
In the event of de-energizing very low ohmic inductances (RL≈0) the following, simplified equation can be used:
E
=
12--

L
⋅
---------V---O----N---(-C---L---)--------
VON(CL) – Vbb
The energy, which is converted into heat, is limited by the thermal design of the component. For given starting
currents the maximum allowed inductance is therefore limited. See Figure 9 for the maximum allowed inductance
at Vbb=12V.
