Part Number: DRV8802 Hi champs,
Woudl you teach me about that DRV8802 do or do not outputs motor-current following under conditions?
xVREF pin: open
DECAY pin: Low
xENBL pin: High
In my understanding, when the DECAY pin is Low, the motor current…

Part Number: DRV8802 Hello,
Our customer use the DRV8802.
The customer limit the start-up current.
When the current hits the current chopping threshold, the current flow reverse in a moment.
What is this?
I attach the scope shot as below.…
Part Number: DRV8802-Q1 Hi team,
VM UVLO rising is 7.8V,typ & 8.2V,max, but what about falling?? Is there a VM UVLO hysteresis or de-glitch in DRV8802-Q1?
Thanks.
Dear, Sir.
My customer is looking for Full-step Stepping motor driver.
The driving current is so small as 67mA.
Regarding DRV8802-Q1 ,
Is it no problem to set ISENA/B chopping current as 67mA?
Best Regards,
H. Sakai
