TPS25750: I2C Pull-up to external 3.3V

Hi team,

Is it ok that I2C pullup to external 3.3V, not a LDO_3V3 when TPS25750 works as I2C slave?

Regards,

Hayashi

    Hi Hayashi,

    I would recommend pulling up to LDO_3V3 therefore the system can still operate in dead battery mode (booting from no-battery or recieving power from Vbus). External 3.3V will also work, you will just lose I2C control in dead battery mode.

    Very Respectfully,
