Web12 de jan. de 2011 · open drain push pull The push-pull output actually uses two transistors. Each will be on to drive the output to the appropriate level: the top transistor will be on when the output has to be driven high and the bottom transistor will turn on when the output has to go low. The open-drain output lacks the top transistor. Webpullup resistors pull the line high when it is not driven low by the open-drain interface. The value of the pullup resistor is an important design consideration for I2C systems as an incorrect value can lead to signal loss. In this article we show the simple equations for the pullup resistor calculation which the system

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. Web4 de jun. de 2024 · Open-drain outputs are useful when multiple gates or pins are connected together, such as with the I2C bus.
