Hello,
We are using two components with unique coin cell backup. The first one is a RTC M41T93SMY6. For this one, I could find AN1011 that states that we don't need external diode and resistor to meet UL60950, it is built in the chip. The second one is a battery switchover STM704SM6F. Could not find anything about UL60950, however the battery is connected directly to the chip without external diode/resistor on all drawings. Are they required, or they are built in like the RTC?
Thanks and Regards,
Hugues Lepage
