Part Number:DRV8818
Hello,
Our customer use the DRV8818.
It occur strange operation.
The customer use 5 pieces the DRV8818.
They assemble them on the one board. One of them at phase B, it occur strange operation.
I attach the file include the waveform.
(Please visit the site to view this file)
The setting of the customer
VM=24V
half step mode
using Mixed Decay: C=1000pF R=56kohm
They connect a capacitor at ISENx pin as 0.1uF
Perhaps, it occur due to noise. But it occur only in Phase B.
Is it possible to occur only in Phase B?
Best Regards,
Naoki Aoyama
