Hi Expert,
Can I change the resistor value between IMON pin and GND? I see in datasheet that the res is all 2.55kΩ.

Hi Elec,
We recommend to use the datasheet typic resistor 2.55kOhm. Since all data on the datasheet is based on R(IMON) = 2.55 kΩ.
If you have to change the R(IMON), it is also should be fine. About the resistor value and related voltage on IMON, please refer to below information:

Hi Jiahua,
Thanks for reply! In above table, why is 2.5V special? According to the parameter, Vimon max is 337uA * 2.25K=0.86V. Does it mean that Vimon should be lower than 2.5V? Thanks!

Hi Elec,
This is our test condition. and to ensure the precision, better to make sure the Vimon less than 2.5V.
