4.2.2
In case of reverse polarity, the intrinsic body diode causes power dissipation. Additional
power is dissipated by the integrated ground resistor. Use following formula for
estimation of total power dissipation
P
The reverse current through the intrinsic body diode has to be limited by the connected
load. The current through sense pins IS1 and IS2 has to be limited (please refer to
maximum ratings on
internally by
4.2.3
In addition to the output clamp for inductive loads as described in
a clamp mechanism for over voltage protection. Because of the integrated ground
resistor, over voltage protection does not require external components.
As shown in
transistor switches on and the voltage across logic part is clamped. As a result, the
internal ground potential rises to
at pin IN1, IN2 and SEN 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 BTS5236-2EKA securely changes to or stays in off state.
