Part Number:DRV8837
Hi,
As mentioned in DRV8837 data sheet, there is no power sequence required for this device.
However, DRV8837 doesn't work normally on customer's board when applying VM and VCC supply voltage at the same time.
On the other hand, DRV8837 works normally when applying VM after VCC is applied.
So, what are the possible causes for this symptom ?
Best regards,
Kato
