Note: The device provides embedded protective functions. Integrated protection functions are designed to prevent
7.1
The TLE7231G is protected against over load or short circuit of the load. After time
channel n switches off and therefore the corresponding diagnostics flag Dn is set. The channel can be switched
on after clearing the diagnostics flag. Please refer to
Figure 7
7.2
A temperature sensor for each channel causes an overheated channel n to switch off to prevent destruction. Then
the according diagnostics flag Dn is set. The channel can be switched on after clearing the diagnosis flag. Please
refer to
7.3
In case of reverse polarity, the intrinsic body diode of the power transistor causes increased power dissipation. The reverse
current through the intrinsic body diode of the power transistor has to be limited by the connected load. The
supply pins must be externally protected against reverse polarity. The over temperature and over load protection are not active
during reverse polarity.
