applications with V
recommended value:
To minimise power dissipation at reverse battery
operation, the overall current into the IN and IS pin
should be about 80mA. 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 via R
the device, this has to be taken into account in the
overall thermal consideration.
Inverse load current operation
The device can be operated in inverse load current
mode (V
not available during this kind of operation (I
case of inverse operation the intrinsic drain source
diode is eventually conducting resulting in considerably
increased power dissipation.
The transition from inverse to forward mode can result
in a delayed switch on.
Note: Temperature protection during inverse load
current operation is not possible!
