is used, VOUT is clamped to Vbb- VON(CL) at inductive load switch off.
17)
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 (I IN = I IS = 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!
Increasing reverse battery voltage capability is simply possible as described on page 9.

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.

using a diode without additional Z-diode VZL, VZb.

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.

A critical component is a component used in a life-support
device or system whose failure can reasonably be expected to
cause the failure of that life-support device or system, or to affect
its safety or effectiveness of that device or system.
Life support devices or systems are intended (a) to be implanted
in the human body or (b) support and/or maintain and sustain
and/or protect human life. If they fail, it is reasonably to assume
that the health of the user or other persons may be endangered.
