Hi
There is no errata or issue observed with PWM frequency.
How are the HALL sensors are connected? Can we verify the HALL type and biasing recommendation including noise filtering as per data sheet?
Are you testing it on EVM?
Please share motor…
Hi Wataru,
Verified for the condition 1, with one HALL fault will not detect and it requires 2 HALL to be disconnected.
For the observation in condition 2, possibility is wrong commutation can be driving motor at low efficiency and causing over temperature…
Hello,
I have not personally used one in a design. Theoretically you should be able to use one in your design.
I would suggest ordering a UCC28950EVM and see if you can modify it to use a hall affect sensor.

Part Number: DRV8353RS-EVM Other Parts Discussed in Thread: DRV8353M , DRV8353 Tool/software: Hello, I want to drive a motor without hall effect sensors. Can I use DRV8353RS-EVM for this purpose? Also can I use DRV8353SMRTAT motor driver for this purpose…
Hi Minhyeong,
Thank you for posting to the Sensors forum!
If you are looking for a smaller EVM to evaluate the DRV5056, one option that you can do is get the HALL-ADAPTER-EVM . The HALL-ADAPTER-EVM is a breakout board that has a bunch of different…
Hi Shlomi,
Just in case, Can you check that the hall connections to the EVM and the jumpers on the EVM are similar to the image below? The configuration shown below is for digital hall sensors.
Also, while spinning the motor by hand, can you provide…
Hi Suy,
It is good that you are getting functionality when you power cycle the board at least. I'm not sure why your other motor is heating up.
1. I think the motor must be identified again if power is reset.
2. You can try to write the CLR_FLT…
Part Number: DRV8353RS-EVM Tool/software: i am running my BLDC motor with DRV8353RS EVM kit with ISO-F28027f MCU board and i am controlling the motor with DRV8353Rx GUI. But when i start my motor then motor starts rotating but the fault led remains on…
Hello,
Thanks for the quick update.
This shows that no inputs are being sent from the MCU.
Double check your hall sensors and make sure that they are connected correctly.
I assume you have the board mounted correctly, but double check that just…
