A drop of the battery voltage while the module is in Sleep Mode leads to a higher device current consumption.
The scenario can be the following:
1. The microcontroller sends the TLE9185xx to Sleep Mode, and goes into Sleep Mode itself.
2. VS/VSINT drops below the monitoring threshold voltage V_POR,f and rises above the voltage V_POR,r. The TLE9185xx wakes up autonomously.
3. Since the watchdog cannot be served, the microcontroller is still in Sleep Mode, after 4 consecutive watchdog failures, the TLE9185xx goes into Fail Safe Mode with higher device current consumption than expected in Sleep Mode without the microcontroller's knowledge.
