TPS65987D: TPS65987D I2C input threshold for LDO_1V8 and LDO_3V3

Part Number: TPS65987D

Hello support team,

I2C high/low input signal spec are defined by two pull up voltage, LDO_1V8 and LDO_3V3. How does TPS65987D set each threshold? Does TPS5987D have any register bit to set it?

Thanks,
Koji Ikeda

    Hi Ikeda-san,

    The TPS65987D I2C input threshold is always set to 1.8V. We have done extensive testing and determined that this setting will work for both 1.8V and 3.3V I2C Thresholds. There is no need to adjust this setting.

    Thank you,
    Eric
