Datasheet «L6207»

Now you are really doing to have to do your own debugging by going through each input and checking the expected values. Media Subscription Media Contacts. That’s the voltage for the H bridge itself, as in the supply for the H bridge part itself and not the logic circuitry voltage.

Distributor Name Region Stock Min. Forget linear voltage regulators because lots of wasted energy. Use of this site constitutes acceptance of our User Agreement and Privacy Policy. Digikey seems to be the only one who has the DIP version in stock: In case it wasn’t clear from the schematic, the supply voltage for the IC is 48 VDC, so that perfectly within range.

Product is in volume production 3. Submit a new text post. Computers and Peripherals Data Center. 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.


L, L, L dual full bridge drivers. Support Home Complete list and gateway to support services and resource pools. Here’s the product page. The device also includes two independent constant off time PWM current controllers that perform the chopping regulation. 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.

General terms and conditions. Don’t forget that the motor inrush is much higher than stall current. Not Recommended for New Design. Key Features Operating supply voltage from 8 to 52 V 5. Arduino has enough current for that coming off the 5v pin. Please contact our sales support for information on specific devices. If you can do SMD work you can get a lot of these chips very cheap. Submit a new link.

You might want to consider using the evaluation board if you can’t debug the layout on your own. Product is in volume production Evaluation: 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.

Current layout and pics can be found here. I can’t tell from your diagram if you did. Become a Redditor and subscribe to one of thousands of communities. However, there still is no voltage between any of the output pins. Buy Direct Add to cart.


Did you also connect some supply power to it. Want to add to the discussion? Product is under characterization. Can somebody tell me what I am doing wrong?

You aren’t going to be powering that chip from the 5V output of the Arduino. IoT for Smart Things. 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. Product is in design feasibility stage. Updated the circuit to the one recommended on page 16 of the datasheet, wired it up like this.

You are missing quite a bit of components to get this chip up and running. Free Sample Add to cart. Reducing torque variation in half step drive. No commitment taken to produce Proposal: Menu Products Explore our product portfolio. Do you have access to a scope? Support Home Video Center. I really want to get this to work You need the common ground.

While it is definately the right way to go, it still didn’t help. Log in or sign up in seconds. Limited Engineering samples available Preview:
