I'm using BQ24296M to charge a single cell li-ion battery. Question I had from the datasheet it was not too clear was that the I2C lines (SDA, SCL, INT) had 10k resistor pull-up to a Vref. The datasheet does not define what that Vref is. I saw there was some mentioning regarding 1.8V on the signals' min and max input/output voltages.
Does the Vref have to be 1.8V or can it be greater, i.e. same voltage that powers the BQ24296M?
