Hello Team,
We are evaluating the use of a supercapacitor as a backup power source for our LoRaWAN module.
Our requirement is to keep the LoRaWAN module operational for approximately 5 seconds during a power interruption. The System required near by 250mA & operating voltage is 5V. We would appreciate your guidance on the most suitable solution for this application.
Specifically, we would like your recommendation on the following:
Considering the short backup duration requirement of only 5 seconds, can the supercapacitor be connected directly without a dedicated management IC?
If a supercapacitor management/charging IC is mandatory, could you please explain why it is required for this application? What are the risks or limitations of connecting the supercapacitor directly without a dedicated IC, and under what conditions would direct connection not be recommended?
We would appreciate any reference designs, application notes, or design recommendations related to this use case.
We look forward to your valuable suggestions.
