Duet Wifi Stepper Driver Chips

[SlimShader]

Hi all,

I managed to blow my E0 stepper chip today by miswiring a new motor. It's done a pretty good job of blowing the chip out.

I had a quick look around and the only ones which seem to be available are the TMC2660C-PA in a 44PQFP package - would these do the job? Looking at the data sheet, the only difference from the original TMC2660-PA seem to be some added low side short protection and quieter motor driving.

The part I'm looking at is 1460-1059-ND on Digi-key UK. Can anybody please comment if this would work with a Duet Wifi?

Thanks!

Colin

TMC2660C-PA

Yes, these are compatible. It looks like TMC have updated them to a new version, and they are backward compatible (according to the spec sheet https://www.trinamic.com/fileadmin/assets/Products/ICs_Documents/TMC2660C_datasheet_rev1.03.pdf, page 47) with old versions.

@slimshader I confirm that you can use either the TMC2660-PA or the TMC2660C-PA.
