Part Number: DRV8802 Other Parts Discussed in Thread: DRV8825 , Hi support team.
I have a question regarding 1Mohm from VMA to VCP.
Could you tell me why this is necessary?
Best regards,
Higa
Part Number: DRV8802 Hi Team,
The voltage dividing resistance is set to VREF. What is the preferred value of the current flowing to VREF?
Is it better for smaller current values? It is necessary to determine the division resistance.

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-Q1 Other Parts Discussed in Thread: DRV8802 Hello Everyone,
We have developed working prototype using DRV8802 motor driver IC, after developing custom PCB we are facing some issues. We have compared voltage values on all the pins…
Hi David,
Q0. May I ask the minimum input frequency as well?
There is no minimum. The inputs can be driven at 100% (no PWM).
As noted in the video, if PWM'ing it is recommended to use a PWM frequency above 20kHz. This avoids the audible range. …
Part Number: DRV8802 Hi
I have some question about DECAY pin.
- Is there Pull-up resister or Pull-down resister at this pin?
- If there is, how much is the resister?
Best Regards,

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.
Part Number: DRV8802-Q1 Other Parts Discussed in Thread: DRV8801A-Q1 , Hi Team,
Can you please help me understand why there is a 1M Ohm resistor between VMx and VCP for the DRV8802-Q1? Also, how come for the same family of devices, such as the DRV8801A…
