5.3.3
When switching off inductive loads, the potential at pin OUT rises to V
current. The inductive output clamp is necessary to prevent destruction of the device. See
The maximum allowed load inductance and current, however, are limited.
Figure 6
Maximum Load Inductance
During demagnetization of inductive loads, energy has to be dissipated in the TLE8104E. This energy can be
calculated with following equation:
The equation simplifies under the assumption of R
The energy, which is converted into heat, is limited by the thermal design of the component.
5.3.4
The TLE8104E provides embedded protective functions. Integrated protection functions are designed to prevent
IC destruction under fault conditions described in this data sheet. Fault conditions are considered “outside” the
normal operating range. Protection functions are not designed for continuous repetitive operation.
Over load and over temperature protections are implemented in the TLE8104E.
