Provide a current path with load current capability by
using a diode, a Z-diode, or a varistor. (VZL < 72 V or
VZb < 30 V if RIN=0). For higher clamp voltages
currents at IN and IS have to be limited to 250 mA.

|Vbb| - 12V if DS is not used (or RIN = |Vbb| - 12V if DS is
used).
To minimize power dissipation at reverse battery
operation, the summarized current into the IN and IS
pin should be about 120mA. The current can be
provided by using a small signal diode D in parallel to
the input switch, by using a MOSFET input switch or by
proper adjusting the current through RIS and RV.
Note that there is no reverse battery protection when
using a diode without additional Z-diode VZL, VZb.
Version c: Sometimes a neccessary voltage clamp is
given by non inductive loads RL connected to the same
switch and eliminates the need of clamping circuit:
