Hi Dave,

Thanks that looks perfect. Though using www.findchips.com does not reveal where I could get a couple? No luke at Digikey etc......

If you have extra's? Want to swap for something....lol

Steve_88, I had forgot to mention that Allegro changed the part number. The attached website has all of the info and samples available. The new part number is A6841.

Thanks everyone, I'll try a few out, I'm sure they are perfect.

I'll be re-desinging a circuit board to use these chips, should I add external diodes?

Thanks,
Steve

Steve_88, If you like, Just make sure you tie the common cathode line on the driver to the supply you are using for the relays and not 5 volts.......
