A temperature sensor for each channel causes an overheated channel to switch off latched to prevent destruction
( also even in case of

7.3
In reverse polarity mode, power dissipation is caused by the intrinsic body diode of each DMOS channel as well
as each ESD diode of the logic pins. The reverse current through the channels has to be limited by the connected
loads. The current trough the ground pin, sense pin IS, the logic power supply pin VDD, the SPI pins and the
watchdog pins has to be limited as well (please refer to the maximum ratings listed on
Note: No other protection mechanism such as temperature protection or current limitation is active during reverse

In addition to the output clamp for inductive loads as described in
available for over voltage protection. The current through the ground connection has to be limited during over
voltage. Please note that in case of over voltage the pin GND may have a high voltage offset to the module ground.
7.5
In case of complete loss of the device ground connections, but connected load ground, the SPOC - BTS5590G
securely changes to or stays in off-state.
7.6
In case of loss of
ground connection or through an additional path from VBB to ground. When a diode is used in the ground path for
reverse polarity reasons, the ground connection is not available for demagnetization. Then for example, a resistor
can be placed in parallel to the diode or a suppressor diode can be used between VBB and GND.
