    Hi Jimmy, It turns out to be a HW issue on our EVM. The pull up resistors on the I2C bus are not strong enough. After changing the pull up resistors (R11,R12,R33 and R34) on TPS23881EVM-083, the frequency is around ~400KHz. We will fix this in our next…

    Hi AndongSun! The two TPS23880 devices will be individually addressed and managed by a host microcontroller. The device I2C addresses are set using pins A1-A4 and must be unique in a multi-device system. Section 9.2 of the TPS23880 datasheet has more…
