Web2.1.2 Logic Control of Open Drain Interface The I2C interface uses an open drain driver with an input buffer to determine logic signals on the bus, which is very different compared to other interfaces that use push-pull drivers. The I2C interface idles in the high state, meaning the signals on the bus are high unless there is communications ... WebWhile I2C devices pull down the lines with open drain drivers or FETs which can in general drive at least about 10mA or more, the pull-up resistor Rp is responsible for getting the signal back to high level. Rp commonly ranges from 1 kΩ to 10 kΩ, resulting in typical pull-up currents of about 1 mA and less.
