Hello

Could you tell me how to terminate the below pins if unused?

C_SBU1, C_SBU2, DEBUG_CTL1, DEBUG_CTL2

Hi Oba,

Debug_CTL1 and Debug_CTL2 should be used as these will determine the I2C address of the TPS65981.

If the C_SBU pins are unused, they can be left floating.

Thank you,

Hi Eric,

Thanks for your reply.
Regarding Debug_CTRL1/2, do I need to terminate High or Low these pins even if I2C is not used?

Oba

Hi Oba,

You could tie DEBUG_CTL1/2 to ground through a 100k pull-down.
