L Datasheet, PDF – Alldatasheet
You might want to consider using the evaluation board if you can’t debug the layout on your own. Distributor Name Region Stock Min. While it is definately the right way to go, it still didn’t help. Did you also connect some supply power to it. ST Code of Conduct Blog. Reducing torque variation in half step drive. Digikey seems to be the only one who has the DIP version in stock: 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.
Become a Redditor and subscribe to one of thousands of communities. Log in or sign up in seconds. Need help with motor driver IC self. You aren’t going to be powering that chip from the 5V output of the Arduino.
Selectors Simulators and Models. Does anybody know why? You need the common ground. 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. The device also includes two independent constant off time PWM current controllers that perform the chopping regulation.
What motors are you using this with as well as how are you getting that 48V DC? Welcome to Reddit, the front page of the internet. Product is under characterization. Forget linear voltage regulators because lots of wasted energy. Limited Engineering samples available Preview: I got an IC for driving two DC motors an STM L in a DIP24 package, datasheet here and I wired it up as illustrated here but when I output the correct logic as described in the l607, there appears to be no voltage datasneet any of the output pins.
Product is in design stage Target: Product is in volume production 3. Submit a new link. Arduino has enough current for that coming off the 5v pin. 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. You need a common ground between the Arduino and motor bridge and the battery. That’s the dataheet for the H bridge itself, as in the supply for the H bridge part itself and not the logic circuitry voltage.
You are at a point where we aren’t going to be able to debug over the interweb.
Key Features Operating supply voltage from 8 to 52 V 5. Please contact our sales support for information on specific devices.
Communications Equipment, Computers and Peripherals. Computers and Peripherals Data Center. Here’s the product page. Submit a new text post.
From the fine datasheet: If you can do SMD work you can get a lot of these dstasheet very cheap. 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. However, there still is no voltage between any of the output pins. Marketing proposal for customer feedback.
