4.2.2
A temperature sensor for each channel causes an overheated channel n to switch off
immediately to prevent destruction. The behavior in case of over temperature can be
configured as follows:
The over temperature flag of the affected channel is cleared by a low-high transition of
the input signal.
4.2.3
In case of reverse polarity, 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
The over-temperature protection as well as other protective functions are not active
during reverse polarity.
