16 ) Integrated protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are not
designed for continuous repetitive operation.
17) not subject to production test, specified by design.
18) The reverse load current through the intrinsic drain-source diode has to be limited by the connected load (as
it is done with all polarity symmetric loads). Note that under off-conditions (IIN = IIS = 0) the power transistor
is not activated. This results in raised power dissipation due to the higher voltage drop across the intrinsic
drain-source diode. The temperature protection is not active during reverse current operation! To reduce the
power dissipation at the integrated Rbb resistor an input resistor is recommended as described on page 9.

To minimize power dissipation at reverse battery
operation, the overall 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.

load
Provide a current path with load current capability by
using a diode, a Z-diode, or a varistor. (VZL < 70 V or
VZb < 42 V if RIN=0). For higher clamp voltages

IIS
The device is specified for inverse load current
operation (VOUT > Vbb > 0V). The current sense feature
is not available during this kind of operation (IIS = 0).
With IIN = 0 (e.g. input open) only the intrinsic drain
source diode is conducting resulting in considerably
increased power dissipation. If the device is switched
on (VIN = 0), this power dissipation is decreased to the
much lower value RON(INV) * I2 (specifications see page
4).
Note: Temperature protection during inverse load
current operation is not possible!

If the device is conducting, the sense current can be
used to reduce the short circuit current and allow
higher lead inductance (see diagram above). The
device will be turned off, if the threshold voltage of T2
is reached by IS*RIS . After a delay time defined by
RV*CV T1 will be reset. The device is turned on again,
the short circuit current is defined by IL(SC) and the
device is shut down after td(SC) with latch function.

between turn on and td(SC).
