- In this video I demonstrate the mosfet module I got from www.ICStation.com
The module has two AOD4184 N-channel mosfets in parallel, which will switch the negative wire on and off. The trigger input has small (in range of 150Ohm) resistor in series and gate has around 10kOhm pull-down resistor. Series resistor limits the current when trigger signal goes high and pull-down resistor keeps the mosfet switched off if trigger signal isn't connected.

I purchased a few of these and use them to drive my peltier cooling modules as well as a heating element. They have never failed me. The PWM comes in handy.
Great video, thanks! Straight to the point and showing exactly how this excellent little module is wired, and how it works. I wish more You-tubers would follow your great example. Thank you!
Thanks for your awesome video for us, looking forward to your further awesome projects.^_^
Can we make an h bridge out of this? What do u recommend for a 12V- 3A DC motor to get drived in h bridge setup.
So does this module still require a flyback diode to prevent the dc motor from back feeding?
i used this to drive RCWL-0516 sinced it's output can't even trigger a 3v relay. this circuit is so inexpensive yet very useful
Can we use a potentiometer on the trigger circuit and varying the trigger voltage with potentiometer will vary motor speed on the output for example? Thanks
Замечательный, информационный контент, спасибо за полезный ролик!
Thanks for the videos. Have you come across a High Side Switch version using P-Channel mosfets that you could recommend? Looking for something to switch the high side of 12V DC circuit.
Sorry, I haven't used any P-channel mosfet modules, so I can't recommend any specific.
Thank you for the reply and please keep up the good work
Hello. Could you suggest me how to use sets of this module to control DC motor rotation direction? Best regards.
Hello, great vid... I see an Arduino... any chance of seeing the test code? The lamp you are using in the vid, what are the specs. .... Thanks in advance. Oh, and keep up the great work...
Great video, thankyou!
Hi
Can I onn or off the module using this directly to a pwm receiver
Hi. Just for clarification, the mechanical switch will be at pwm terminal and positive input terminal ?
Sorry if this was explained, but can I use this module with a low voltage (5.5v max) capacitive touch switch? And if so, do I need to power the capacitive switch separately or can one of those pins be used to power it? I think you explain this a bit but it’s hard for me to grasp it because I’m so new with electronics.
So this mosfet for protect little micro switch from high current, is that right?
Can make a video using ir handsweep on/off switch?
Have you schematic for 2 mosfet transitors & OHM & KOHM? :)
Hi, how is possible to controll it from rc receiver with pmw signal?
D8184 If i Need 200W input it is enough with 5V input??
I want to make a 12 volt control of the cassette player to start DC DC up coverter which from 12 volts to raise voltage in a car to 36 volts and to supply TDA7498E. How many amps will pass at 12 volts of impulse beats from the bass. To start the mosfet, current is taken from an electric antenna on a cassette player remote control.
Hi, how much voltage we can send to the trigger pin?
How do you mount heatsinks on this module?
One more question, what are the wires and connectors you have going from the Arduino to the module? I'm so new to electronics that I don't even know if these pins are a standard size and spacing and what the connectors and pins are even called and where to get them. I assume amazon? I'd love to get a kit of all these types of connectors if they are available. I feel so stupid asking such basic questions but no one knows who I am here so that's good, haha.
Thanks great video
okay to use it for hv cap dump circuit ?
I would recommend using a mosfet gate driver between the AOD4184 and an MCU. The ON resistance is much higher with low gate voltages. I burned 3 of these modules trying them with airsoft DC brushed motors.
Flyback diode on the motors and maybe a Zenner on the MOSFET? Are you sure they overheated? (Solution, in this case, heatsink and/or gate driver). I'm just curious, you identified a failure mode and I intend to use this module.
@@milutzuk It's been a while, but I think I had a flyback diode for the motor. The MOSFETs weren't running warm once ON. My motor had an inrush current of around 30 amps, and I think if the rising edge on the gate was too slow, it instantly heated up and failed short. There probably was some back EMF in reverse when the airsoft motor stopped, due to the spring making it run in reverse. I didn't have an oscilloscope at the time to check for back EMF. I need to experiment again.
@@Canilash Thank you. That makes some sense. I don't bet any money but the MOSFETs have some caloric capacity to soak the starting thermal transients and the driving pulse on the gate couldn't be that slow (and when used in PWM the MOSFETs will run noticeably hotter), I still think the most probable cause is voltage transients. Especially when using brushed motors which connect and disconnect coils very fast. Also, the noise can be induced in adjacent wires or traces. I know in the past Zenner diodes were used, in such cases, to limit the voltage on both D-S and G-S. Anyway, I don't design everyday electronic circuits and I'm a bit rusty here. (also sorry for my awkward English, not a native speaker). Thank you again.
Edit: a gate driver really makes sense in almost any case, it can protect both the MOSFET and the driving circuit and I wonder why they didn't put something like that on this module, I mean it's a module, right? If it's too simple I may not be tempted to buy it, I can slap 4 TH parts in a PCB and wire them in 20 mins, but I may be tempted to buy it if it's versatile and cuts me a lot of working and designing time.
Can I change N-channel Mosfet to P-channel and then connect power supply in reverse polarity (IN- to plus, IN+ to minus)?
When I attach input and output (without module +- power) my led attached is on. Why ? I use RPI GPIO.PWM(21,100-10000hz)
can I start this power module with a 5V dc input , without an arduino ?!
Sorry for late reply. Yes, this mosfet module can be triggered/turned on without microcontroller.
is there a manual for this?
better than relay ?
For switching DC current on and off, yes. Relay's coil needs significant amount of current, while mosfets don't. Relays have moving parts, which may go bad due to (for example) arcing. Also, relays can't be used in applications where PWM is needed (dimming lights for example).
How much the ampere output result
Don't you need a flyback diode?
For inductive loads, such as relays and motors, this is pretty much a standard. In the video, only a led was used therefore it wasn't necessary.
