6.2
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
polarity mode.
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
ground pin (GND) is limited internally by R
polarity.
6.3
In addition to the output clamp for inductive loads as described in
over voltage protection. Because of the integrated ground resistor, over voltage protection does not require
external components.
As shown in
voltage across logic part is clamped. As a result, the internal ground potential rises to V
zener diodes, the potential 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 BTS5235-2G securely
changes to or stays in off state.
