Unused ADCIN0-4 on TPS65950

Other Parts Discussed in Thread: TPS65950

Hi

What is the purpose of grounding the unused ADCIN signals on the TPS65950?  Is it for power savings or can it cause harm to the part if they are not grounded?


Thanks

Nate

    Hi,

    ADCIN0 and ADCIN1 are tied to battery functions and have to be grounded when BCI is not used.

    Other ADCINs should be grounded as we dont want any erroneous signals on these pins. ADCIN3 and ADCIN4 have muxed functionality.

    Hope this helps.

    Gandhar.
