Please support me on Patreon: … '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… Web19 de mai. de 2024 · The open collector/open drain pin will sink current into GND.
