NOTES
:
In case of over current or short-circuit, the device will not report the fault to the status pins. The output current will be limited to the Ilim value. The device will probably
heat up and in this case the overtemperature detection will be triggered. If so, the output will be turned off and the fault will be reported to the status pins.
