Just for the record As Full Icecat channel partner login to see all product data or request a Full Icecat subscription. I’m glad to hear that this datasgeet worked well for you! Try one of these Digikey part numbers, it’s not very critical: 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.

These large current draws make the supply voltage drop, unless your power supply can handle it. Well, I’ve certainly been finding both of your advice very helpful! This technique is known as “chopper drive” and it allows the motor to increase its top speed.

This seems to be discontinued.


Another reason for separating the supplies is to prevent noise from getting back into the microprocessor. Category Machines used for washing clothes. When it falls back down, the power is reapplied. What I don’t understand is Can you give me a part number?? I want to find the easiest possible solution for each circuit. I guess the stuff datssheet wrote here could be turned into a nice article for the website.


What you need around a is just 2 capacitors per side. The l can create the control signals for bipolar, unipolar and variable reluctance stepper motors.

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. If you do want the chopper drive I think OnSemi will still send dataeheet a few dozen or so free diodes as samples, but you have to pay shipping now it seems: I have a few questions about dtasheet I have found so many different diodes.

BTW Arduino is designed always on Eagle. Front-load, Colour of product: As Massimo says, you shouldn’t load the Arduino with anything more than a few milliamps! Also, maybe I’m confused, but I was thinking, can I use the ld instead of the L??

After this, I intend to make a circuit using the l and the ULNB to control a unipolar stepper. Browse by Manufacturer Get datqsheet insight into any electronic component.


Product name is a key part of the Icecat product title on a product data-sheet. Also, I have not yet tried any circuits!! I’m datasueet that these chips are on their way to retirement!! Is there some other setup which I should be investigating??

This is used for giving the reference voltage for controlling the Chopper circuit. Some manufacturers license their brand names to other producers. You can use it with unipolars. However, STMicroelectronics assumes no responsibility for the consequences of use of such information nor for any infringement of patents or other rights of third parties which may result from its use.

I don’t understand how to select the appropriate one. Can anybody explain how to connect up this pin?? 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.
