You might want to consider using the evaluation board if you can’t debug the layout on your own. It’s wasn’t very obvious from his fritzing diagram that the little black barrel jack is where he is bringing in the bridge supply.

Strictly speaking, I’m not running a motor with it but actually an electromagnet, which acts as the stator for a linear motor. No commitment taken to produce Proposal: Menu Products Explore our product portfolio. If you just need something to power small motors say toy DC motors look at this: Do you have access to a scope?

Marketing proposal for customer feedback. You are missing quite a bit of components to get this chip up and running. Arduino has enough current for that coming off the 5v pin. Product is in volume production Evaluation: The OP has attached the 5v to the VREF pins which are used to figure out the signal voltages so it knows what’s high and low. Digikey seems to be the only one who has the DIP version in stock: Right now looking at it your Arduino ground isn’t tied.

L Datasheet, PDF – Alldatasheet

The device also includes two independent constant off time PWM current controllers that perform the chopping regulation. Submit a new text post. Want to add to the discussion? While it is definately the right way to go, it still didn’t help. Please refer to page 16 of the datasheet. Cloud Components and Modules.

Support Home Complete list and gateway to support services and resource pools. However, there still is no voltage between any of the output pins. Don’t forget that the motor inrush is much higher than stall current.

Key Features Operating supply voltage from 8 to 52 V 5. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. I still stand by the fact that he really needs to look at the REF circuit that ST provides on page Forget linear voltage regulators because lots of wasted energy.

Submit a new link. Communications Equipment, Computers and Peripherals. Need help with motor driver IC self. From the fine datasheet: You aren’t going to be powering that datasneet from the 5V output of the Arduino. o6207


ST Code of Conduct Blog. Current layout and pics can be found here. I can’t tell from your diagram if you did.


Datsheet torque variation in half step drive. Also, if you are really going to be running the full current capacity through this chip then the bread board is going to get a little angry.

L, L, L dual full bridge drivers. I also should have mentioned earlier that although there is no real voltage to speak of between the output pins to speak of, what little there is 0. Please contact our sales support for information on specific devices. Not Datashete for New Design.

You need a common ground between the Arduino and motor bridge and the battery. General terms and conditions. It would be helpful in this situation.

I’ll try that ASAP! Did you also connect some supply power to it. Selectors Simulators and Models. Support Home Video Center. Now you are really doing to have to do your own debugging by going through each input and checking the expected values. What motors datazheet you using this with as well as how are you getting that 48V DC?
