microstepping with L6258

Posted on May 17, 2011 at 10:18

Hello,

I work on a microstepping board using the L6258, but even if I follow ST data sheet, my board allways burn.

I don't understand why because the PCB seems allright and I let a specialise firm to solder my powerSO36.

There's few mistakes with this chip especially the disable pin which much be high to be disabled and the phase changing that you musst program.

If somebody has developped or work on such a board all advices will be welcome.

Thanks.
