Does a battery (CR2032 button cell) need extra protection like a diode and current limiting resistor when this battery is connected to the PCF85263A? The explanation of the battery switch circuit inside the PCF85263A is very minimal.
Additional question: What is the leakage current on VBAT when VDD is active?
The typical application (datasheet):
Needed according to UL:
Proposed application:
