Need recommendation for Full Bridge Driver
Posted on October 26, 2014 at 05:55I need a Full Bridge driver IC capable of at least 2.5 Amps at 125 kHz.The L6225 connected in parallel looks good but the highest frequency is only rated to 100 kHzIs there a higher frequency version of this or can...
Motor Electrical parameters Rs and Ls
Posted on October 21, 2014 at 02:19Gigi: I have a question, measured in workbench Motor Electrical parameters Rs and Ls. I see ST data is used RLC meter measurement frequency at 100 Hz, but the motor is running in the PWM 16K frequency, wheth...

Bad Overheating problems with L6474 , Help!
Posted on September 05, 2014 at 03:36I'm finding that the L6474 runs terribly hot even at 1.4 amps . Its on a decent PCB with 20 plates thru tholes a small heatsink (1'' x 1'') on the back and it will rise to 110 C in less than 2 minutes . It is the...
L6480 - first move after STBY/RESET sometimes fails
Posted on October 08, 2014 at 14:53Hello.We are using the L6480 with a Fulling FL86ST67 motor driving a drum sorter.As a security measure, there is a light curtain asserting the STBY/RESET pin for every object entering. The first move (by 200 steps)...
L6470H discovery Issues on two systems
Posted on October 02, 2014 at 22:29I am attempting to run the L6470H discovery kit with the dspin software from a machine with windows xp on it. I was previously able to run it from another machine with xp, I installed the same files but cannot conn...
L6472 Spurious Over Current
Posted on September 26, 2014 at 22:05I'm having a similar issue as someone else posted last year. We had problems with overheating of the IC, so I increased the slew rate and that helped. But now, we're seeing random over-currents and I am wondering...
L6470 High Speed Issue
Posted on September 18, 2014 at 21:39Dear Motor IC Forum: I am using an L6470 to drive a stepper motor attached to a gearbox and am not able to achieve step rates greater than roughly 700 steps/sec with any microstepping setting. The motor gets loud...
