The transistor may burnt. You are limited to a current of about mA. For a mA current you then need a seriesresistor of 33 Ohm. At 5 Volt GS it can however only take some 4. Backyard controller design Eric’s Arcana and RiderX. I datwsheet not sure what datasheet you looked at but I do not see a max of 4Volt, I see a max of ca 20 Volt. Notify me of new comments via email. Switching speed indeed is important.

Also the and will be more efficient with this circuit. I just touched the gate pin to turn motor on. So, the bottom line is: You need a logic fet for that such as the IRL series. Rds 38mOhm with a Vgs of 3. So if yr gate voltage is 5Volt, your source voltage will never be above that. This site uses cookies. The is somewhat better: In my schematic I use an output with a small resistor Ohms in series with the gate of the N Channel Mosfet STP3NA and my load is in drain like the first schematic showed in this post, but I have no R1 resistor between gate and source, I only have a resistor like R1 in the second schematic.

My hairs are starting to turn gray: You are commenting using your Facebook account. I had a IRF Mosfet but now i understand why it became very hot. I even used feedback protective diode with motor. Another thing to beware of in datasheets is Vthresh threshhold voltage.

Or am I overlooking something? The only conditions are it should have high switching speed so low rds on and high break down voltage. If for instance you want to switch 5A in a 12V circuit and you only want to waste 0. The battery is ok and gives a steady 4 volts. The relatively cheap BUZ11 is also an option.


Thanks a lot for this excellent article. If it does open at 3 volt and your PIC supplies that, adding a transistor is not really necesary and if you do it doesnt need to be the BC, can be a regular signal transistor too, like the The dissipation then is 5x5x0.

But suppose the FET you choose has 0. I presume you are aware of the designcriteria of an H-bridge and the chances of shorting your PSU if you dont do the switching correctly. Apologies foe my late reply.
