recommended value:
To minimise power dissipation at reverse battery
operation, the summarised current into the IN and IS
pin should be about 50mA. 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 R
Since the current through R
heat in the device, this has to be taken into account in
the overall thermal considerations.
V
load
Provide a current path with load current capability by
using a diode, a Z-diode, or a varistor. (V
V
currents at IN and IS have to be limited to 250 mA.
