LTC2943 Gas Gauges

Dear all,

I have a question about the bus I2C for LTC2943.

Actually, I put a pull-up resistors with 10k between the 3V3 and the bus I2C.

Unfortunately, I can't understand why the communication failed by using 10k resistor pull-up?

on the other hand, when I put 2K pull-up resistor, LTC2943 work correctly.

Could you please help me to resolve this issue.

In the datasheet, I didn't find information about the value of the currents and voltage should be applied on the I2C pins.

Only in the schematics of typical application we can see the 2K resistors pull-up!

Tank you in advance for your support!
