Description
Hi there!
I'm using the ESP32-C3 with the Arduino Framework.
The system uses a battery as backup for AC Power Source, and it works okay. However, when the battery drains too much, the system stops working. Additionally, when the AC Power is restored, it recharges the battery, but the system doesn't resume working. I need to completely turn off and turn on again in order to back working. "Hardware Reset".
Do you know of any system functions or calls that can detect when the system halts/fails for any reason? Perhaps I could detect a "brownout event" and take some actions accordingly?
Thank you in advance.

Other Steps to Reproduce
Decrease the voltage until it stop working, and then get the voltage back to an operating range.
I have checked existing issues, online documentation and the Troubleshooting Guide
