OMAP 3503 with TPS65950 RTC battery circuit

Other Parts Discussed in Thread: OMAP3503, TPS65950

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
