Thanks for helping out a slow learning electronics geek wanabe!

Could you give me a link to one like you recommend?? I’m getting closer to actually trying to build this thing! I’ll post some picures of that too under a different topic. I put the whole circuit in a Hammond B box, and the box acts as a heatsink. Forget the “IC Bridge” diodes A designer might use 5 volt steppers and then run them at 12 or 14 volts. I think OnSemi will still send you a few dozen or so free diodes as samples, but you have to pay shipping now it seems: Product name is a key part of the Icecat product title on a product data-sheet.

Would you recommend another IC or is it cheaper to use seperate diodes?? You keep coming to my rescue I am planning to try the schematic on the l datasheet. As Full Icecat channel partner login to see all product data or request a Full Icecat subscription.

If you want to control a unipolar stepper, you can use the l with the LB or any darlington transistor array. Front-load, Colour of product: Sounds like you aren’t an electronics newbie anymore, you’re doing great!


The driver will draw such large currents that connecting it’s power suply to the Arduino’s risks passing the power supply transients back to the Arduino. I will investigate tonight, but perhaps you can explain Use a separate supply.

In my stepper driver, I used.

In the diagram they call them ‘fast diodes’ which is synonymous with Schottky diodes. In terms of the 12V motor supply and the clean 5v supply, the answer lies with the motor.

I’m not sure if you would need a buffer. L datashet pdf I’m just a beginner still! How do I know when it is adjusted right??

It includes two PWM chopper circuits to regulate the current in the motor windings. The l has another important feature. A manufacturer can have multiple brand names. I’m interested to compile a group of circuits to control both unipolar and bipolar steppers, that offer a range l62100 price vs functionality options.

If you want to control a unipolar stepper, you can use the l with the ULNB In all cases, you will need a few extra components to complete the circuit. Please post if you already have a good solution for one of these circuits.

Also I have a nice working circuit that uses a TTL shift counter as the transalator. I’ve been looking at lots of different solutions and right now I think that using the l chip is probably the best balance of features, price and useability. As Massimo l620, you shouldn’t load the Arduino with anything datazheet than a few milliamps! I’m planning to breadboard the circuit very soon, so I will post some pictures of that, and the final schematic that I use.


Usually application needs at least 5 hours for publishing information about new products. L62210 that this responsive data-sheet is included in the product page of your webshop.


What is their purpose?? Well, I’ve certainly been finding both of your advice very helpful! You can use it with unipolars. So, if I run datasjeet on a 12V power supply, don’t I get the clean 5V and unregulated 12V that i need? This is used for giving the reference voltage for controlling the Chopper circuit.

I would like to compile circuit designs using the l datasueet control bipolar and unipolar steppers, with and without chopper control. Some manufacturers license their brand names to other producers.

I’m glad to hear that this one worked well for you! This seems to be discontinued. The diagram suggests using the L which is a ‘2 schottky bridge motor controller’.

Multiple product codes can be mapped to one mother product data-sheet if the specifications are identical. Also, i’m still wondering These large current satasheet make the supply voltage drop, unless your power supply can handle it. When a stepper motor turns on, it draws large amounts of current into its windings. You are asking for unpredictable trouble if you do.

I think Massimo is in Sweden and I am in Canada, near the datashheet, so here is part two of your international answer! Category Machines used for washing clothes.
