Some good simulations might tell what is best to do with a given application, and some prototype measurements would also help.

Igf511 get my h-bridge to move, i need sensor, mine is a ir sharp range finder on a servo motor i might also make a version with an lcd screen and sonar range finder datadheet see in total dark the range finder moves of 1 degree, takes the range of the object in front of it and repeat, like a sort of sonar.

Will i be fine to use only the irf on my robot?

Articles Top Articles Search resources. They both say using the body diode for inductive current can blow the fet. Read these app notes from International Rectifier and Fairchild about mosfets I need to build a h-bridge for my mobile breadboard aka hammerhead cause of its shape. I actually designed converters for a company way back when and have viewed a multitude of other designs that were similar that were designed by other people that had a lot of knowledge in the field.

It gets even worse if you are in an h-bridge configuration. That is probably just something added by the creator irr511 that web page. On the other hand, a very high speed H bridge may benefit from adding extra diodes because doing that, if not anything else, moves some of the heat out of the transistor package and therefore keeps it cooler.

Sure, many people get away with it, but why take the chance when a simple schottkey is much better at the job anyway. On the other hand, if the device overheats or has to be used in high heat environment then datwsheet would probably not work well to use that internal diode.

Thread starter breadboardguy Start date Jul 22, Adding an extra diode would really be silly here. You must log in or register to reply here. I can state that it is a fact that there are many power converters out there that do not use an ‘extra’ diode in parallel with the MOSFET, and depend entirely on the integral body diode to take care of the back emf of datashete inductive loads.

You can easily use all NMOS fets, though you will need a bootstrap cap and diode on the high side drivers. Was thinking single direction, even though you obviously said h-bridge.

I did all the schematics with some features like all inputs high impossible so no short but as i am a newb For a better experience, please enable JavaScript in your browser before proceeding. It dose say It has source fatasheet drain diode built in for inductive loads.

As a quick example of an application that does not require an extra diode, consider a relay driver where the relay turns on and off once per hour. Read the app notes. By freewheel diode, do you mean fly back diode?

As a final note, we’d also have to look at the effect of the negative voltage on the drain when the diode conducts, irrf511 might force us to have to use a gate drive signal that actually goes a little negative rather than to zero as many designs do N-MOSFET application. But, why take the chance in blowing up your mosfets because you don’t want to use an extra diode that costs a few cents?

However, i have a geometry question that is burning my lips but i only see my father in two days It so funny how people datashert read for themselves It has source to drain diode built in for inductive datashewt. Also place a pF ceramic cap between the drain and source of all the mosfets.

Thank you if you post of course. 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. Just saying hello Started by MichaelaJoy Yesterday at 6: Potentiometer Questions Started by norbss Yesterday at 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. I have doubts that it is a more practical way of doing with npn and pnp combo I also need to know where daatasheet place the flyback diode please.
