Hi,
I am using OMAP3503 with the TPS65950 and have two questions regarding the RTC battery circuit.
1) Is there a diode built into the TPS65950 on pin M14 so I can directly connect to the battery? Presumably there is since the schematic check list says to tie M14 to ground if you are not using a backup battery... but I would prefer confirmation.
2) I am planning on using a standard 3.3V coin cell, lithium battery. Is this OK as long as I do not turn the charger on?
Thanks,
Tony
