4.2
The device provides embedded protective functions. 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 neither designed for continuous nor repetitive operation.

The load current
ground. There are multiple steps of current limitation
automatically depending on the voltage drop

typical device.

Depending on the severity of the short condition as well as on the battery voltage the
resulting voltage drop across the device varies.

In the event that either the short circuit detection via V
on chip temperature sensor senses over-temperature before the blanking time t
expired, the device switches off resulting from over-temperature detection. After cooling
down with thermal hysteresis, the devices switches on again. Please refer to
for details.
