It so funny how people never read for themselves It satasheet source to drain diode built in for inductive loads. Sorry, was braindead on the diode. Right on the motor if you can. Nope the man that quoted it on his web site is right it tells in the data sheet read it’s on the first page here a quote.

They are incredibly enlightening. Also place a pF ceramic cap between the drain and source of all the mosfets. Orf511 helps reduce the ringing effect from the transistor turning on and off.

Some good simulations might tell what is best to do with a given if511, and some prototype measurements would also help. I did all the schematics with some features like all inputs high impossible so no short but as i am a newb Place the freewheel diode as close to the motor as possible.

Read the app notes. Replacing a 4 pin leaded inductor with a 2 pin Started by gkmaia Yesterday at If you look on any data sheet you will find that that particular diode has a rather high forward voltage, much higher than an external Schottky would have for example. However, i have a geometry question that is burning my lips but i only see my father in two days Media New media New comments Search media. Yes, but it says nothing about using it for inductive loads.

If so, because the current will go in both xatasheet in the motor, placing a diode will shortcut the whole thing.

Read these app notes from International Rectifier and Fairchild about mosfets Just saying hello Started by MichaelaJoy Yesterday at 6: On the other hand, if the device overheats or has to be used in high heat environment then it would probably not work well to use that internal diode.


The integral body diode sees a current spike once per hour that lasts datasheeh 1ms or maybe even 10ms, but after that it has almost 60 minutes to cool back down.

Started by fastline Yesterday irt511 8: Forums New posts Search forums. This is probably the biggest factor in determining if you can use the internal diode or not.

BEAM Circuits — Steve Bolt’s H-bridges In my drawings i only used n-channel irf to source the motor and to complete the circuit to the – terminal of the battery but on that website, two type are use npn and pnp.

That just seems silly to me. By freewheel diode, do you mean fly back diode? Potentiometer Questions Started by norbss Yesterday at
