5.3.4.1
The TLE8104E is protected in case of over load or short circuit of the load. The current is limited to I
time t
The over load flag (CLn) of the affected channel is cleared by the rising edge of the CS signal after a successful
SPI transmission. For timing information, please refer to
Figure 8
5.3.4.2
A dedicated temperature sensor for each channel detects if the temperature of its channel exceeds the over
temperature shutdown threshold. If the channel temperature exceeds the over temperature shutdown threshold,
the overheated channel is switched off immediately to prevent destruction. At the same time (no delay), the over
temperature flag Tn is set. After cooling down, the channel is switched on again with thermal hysteresis ∆T
The over temperature flag of the affected channel is cleared by the rising edge of the CS signal after a successful
SPI transmission.
5.3.5
In the case of reverse polarity when outputs are turned off, the intrinsic body diode of the power transistor causes
power dissipation. The reverse current through the intrinsic body diode has to be limited by the connected load.
The V
over temperature are functional in reverse current operation.

supply pin must be protected against reverse polarity externally. Please note that neither the over load nor
, the corresponding over load flag CLn is set. The channel may shut down due to over temperature.
