Hello
The condition for turning on the constant current of the LTC4311 is that VTHR = 0.55V & Slew rate exceeds 0.5V/us.
When using the LTC4311, I am worried that the rising edge may be erroneously detected and the constant current may be turned on…

Hi,
Hi Montea,
When the bus signal begins to rise, the current is flowing through the pull-ups. As soon as the VTHR level is crossed, the LTC4311 injects a controlled amount of current and drives the bus up to ~VCC-0.4V. Then the pull-ups take the signal…
A lot depends on loading of the bus and the speed you are running. The logic 1 is limited by the RC time constant of the pull up so there is a limitation and tradeoff between speed and power that way.
You can also use accelerators like LTC4311
