6.2
In case of reverse polarity, the intrinsic body diode causes power dissipation. Use following formula for estimation
of total power dissipation
The reverse current through the power transistors has to be limited by the connected loads. The reverse current
through the ground connection has to be limited either by a resistor or by a pair of resistor and diode. The current
through sense pins IS1 and IS2 has to be limited (please refer to maximum ratings on
protection is not active during reverse polarity.
6.3
In addition to the output clamp for inductive loads as described in
over voltage protection. The current through the ground connection has to be limited e.g. by a resistor.
As shown in
across logic part is clamped. As a result, the ground potential rises to V
the potential at pin IN1, IN2 and CLA rises almost to that potential, depending on the impedance of the connected
circuitry.

In case of complete loss of the device ground connections, but connected load ground, the BTS5242-2L securely
changes to or stays in off state.
