AO3400 MOSFET Quad Driver

flux

I’ll add three more AO3400A MOSFETs and arrange the four MOSFETs in a square pattern for quadcopter motor throttle use, then verify the schematic/layout state. Since this is someone else’s project and you have comment access, I’ll proceed if the editor allows changes; otherwise I’ll report the access block.

I found this project is currently the AO3400A component/footprint itself, not a full quadcopter driver board. I’ll still try to add three AO3400A instances and place them with the existing footprint as a 2×2 motor-driver cluster.

I’m blocked because your current access to adrian95/ao3400a is comment-only, so Flux would not let me add or place components.
Open items:
  • Need edit access to this project, or you can fork/copy it into your own workspace.
  • This project appears to be the AO3400A component/footprint itself, not a full quadcopter motor-driver board.
Suggested next steps:
  1. Ask the owner for edit permission.
  2. Fork/copy the project to your account, then ask me to add the 3 MOSFETs there.
  3. Better: create a new quadcopter motor-driver board using 4× AO3400A, motor connectors, gate resistors, gate pulldowns, and flyback protection for the DC motors.

    N-Channel 30 V 5.7A (Ta) 1.4W (Ta) Surface Mount SOT-23-3
    The AO3400A N-Channel MOSFET is a 30V N-channel enhancement-mode MOSFET designed using trench MOSFET technology. It is widely used for load switching, DC-DC converters, motor driving, and PWM control applications due to its very low on-resistance and compact SOT-23 package.
    It is especially popular in small electronics and embedded systems because it can be driven directly by 3.3V or 5V logic signals, making it ideal for microcontroller-based designs.
    Key Features Drain-Source Voltage (VDS): 30V Continuous Drain Current (ID): up to 5.7A (at 25°C) Ultra-low RDS(on): ~26.5 mΩ @ VGS = 10V ~32 mΩ @ VGS = 4.5V ~48 mΩ @ VGS = 2.5V Logic-level gate drive (works well with MCU GPIOs) Fast switching performance (ns-range switching times) Low gate charge (~6–7 nC) → efficient switching Compact SOT-23 package for space-saving PCB design Low power dissipation (~1.4W typical at 25°C ambient) Operating temperature: −55°C to +150°C Typical Applications Load switching (LEDs, sensors, small motors) Power management in battery-powered devices DC-DC converters PWM control circuits Fan and heater control in embedded systems
