Hi Team,
Is there any way to evaluate the working current on SCLB and SDAB pin? We can only find quiescent current spec in the datasheet.

What do you mean with "working current"?
"Quiescent" means that the I/Os are not switching. The datasheet lists the supply current for both high and low states; the total supply current depends on how much the I²C bus is in each state.
The current sunk by the outputs when they are driving low depends mainly on the pull-up resistor values, so it cannot be specified in the datasheet. Use I = (VCC − VOL) / Rpullup, where VOL is about 0.5 V.
