In RTC PCF85363ATL/AX and PCF85263ATL, Internal battery switchover circuit is present. Also both the parts are UL listed part.

My question here is--> Do we need to add series resistor or diode or both for the battery protection. Is there any internal current limiting protection on battery pin and also is any protection diode internally.

Satish
