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 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 … Web11 nov. 2024 · How many watts does an LED bulb use? LEDs have a higher wattage than incandescent bulbs. You can use LEDs equal to 100 watts in a 60-watt fixture. Let me …
