Web27 de jun. de 2016 · The open collector (BJT) or open drain (FET) is essentially a SPST switch connecting the IC pin to ground. If the switch is closed, then the voltage on the pin (and the I²C line) is about 0 volts. If any switches are closed (if any pins of any ICs are connected to the same SDA or SCL line), the voltage on the line is about 0 volts. WebWhen the device exits the POR condition (releases reset), device operating parameters (i.e., voltage, temperature, serial bus frequency, etc.) must be met to ensure proper operation. … 'Open drain output' is analogous to open collector operation, but uses a n-type MOS transistor (MOSFET) instead of an NPN. An open drain output connects to ground when a high voltage is applied to the MOSFET's gate, or presents a high impedance when a low voltage is applied to the gate. The voltage in this high impedance state would be floating (undefined) because the MOSFET is not conducting, which is why open drain outputs require a pull-up resistor connecte… jira powershell rest api
