4.2.2
In case of reverse polarity, the intrinsic body diode causes power dissipation. Use following
fomular 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
4.2.3
In addition to the output clamp for inductive loads as described in
mechanism for over voltage protection. The current through the ground connection has to be
limited e.g. by a resistor.
As shown in
opens and the voltage across logic part is clamped. As a result, the ground potential rises to V
-
that potential, depending on the impedance of the connected circuitry.
