TPS25821: Not able to source 1.5A to Samsung phones

Chris Benwell

Part Number: TPS25821
Other Parts Discussed in Thread: TPS25820,

Tool/software:

I have also observed that the TPS25821 is only able to negotiate standard USB current and this results in a Samsung phone displaying a warning message. Can the TPS25820/21 provide 1.5A to Samsung phones?

Hi Chris,

Thank you for reaching out!

Most Samsung phones implement BC1.2 to allow for faster charging from non-PD sources. The TPS25820/21 do not support BC1.2 charging protocol.

If BC1.2 support is needed, I recommend looking into the TPS25814 instead.

Best Regards,
