Dear Support team,
Good day.
I have a problem of I2C communication error with P82B96 on our board.
It seems to I2c receiver can't receive I2C address & data
due to Low voltage floating(≒1.08) of SCL/SDA outputted from P82B96. ※with 4.7~2.2kΩ pull-up
In general, I think I2C Vth(Low) spec of receiver is 0.3 Vcc as I2C standard,
If Vcc = 3.3V then Vth(Low) is 0.99V.
However P82B96's Vol spec - Max = 1V can not meet 0.99V as above calculation.
In addition, pull-up current also pulls up the I2C-Low voltage,
I think this Vol spec is barely below the level for normal I2C communication.
Could you help me to answer the following questions.
(1)My understanding is correct or not about Vol spec?
(2)Solution to fix my I2C communication error.
