ST Code of Conduct Blog. Do you have access to a scope? IoT for Smart Things. Product is in volume production only to support customers ongoing production. Product is in volume production 3. You need a common ground between the Arduino and motor bridge and the battery.
The device also includes two independent constant off time PWM current controllers that perform the chopping regulation. If you can do SMD work you can get a lot of these chips very cheap. Marketing proposal for customer feedback.

You need the common ground. I’ll try that ASAP! Forget linear voltage regulators because lots of wasted energy. 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.
Right now looking at it your Arduino ground isn’t tied. 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 datasheet, there appears to be no voltage between any of the output pins.
You are at a point where we aren’t going to be able to debug over the interweb. Can somebody tell me what I am doing wrong?
I can’t tell from your diagram if you did. Please contact our sales support for information on specific devices.
Product is in volume production Evaluation: From the fine datasheet: Who We Are Management. Submit a new link. I still stand by the fact that he really needs to look at the REF circuit that ST provides on page What motors dztasheet you using this with as well as how are you getting that 48V DC?
Need help l620 motor driver IC self. Don’t forget that the motor inrush is much higher than stall current. No commitment taken to design or produce NRND: Log in or sign up in seconds. This device needs some external caps and resistors to get the charge pump to operate that drives the upper fets of the integrated h-bridge.
Not Recommended for New Design.
Current layout and pics can be found here. Strictly speaking, I’m not running a motor with it but actually an electromagnet, which acts as the stator for a linear motor. While it is definately the right way to go, it still didn’t help. However, there still is no voltage between any of the output pins. Distributor Name Region Stock Min.
