Web'Open drain output' is analogous to open collector operation, but uses a n-type MOS transistor (MOSFET) instead of an NPN.: 488ff An open drain output connects to ground … 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. Web18 de ago. de 2024 · The reason of why the i2c lines are open drain is (please review and correct me if I missed any point)- I2C is multi-master and multi-slave protocol.If the lines are not open drain then there may chance that one slave pulling the device low and other slave is trying to pull the same line high.This situation is called as the bus contention. siberian white crane
