Part Number: DRV8462 We have this driver set up with a STM uP. We are noticing that is getting rather hot when the TI's eval board stays relatively cool. What would be some items to look into to ensure we're set up correctly?
Looking at design…
Thanks Grzegorz for your additional pointers to Ahmed.
Hi Ahmed,
I assume all your issues with getting the DRV8462 driver to function were resolved. Please go ahead and close this post. For future questions you're welcome to start a new thread. Thanks…
Perhaps, what my question really is...can this TI driver achieve phase current results similar/same to what the last image shows? Now, I can get a custom motor spec'd but I'm needing to understand if this driver can regulate the current well enough to…
Part Number: DRV8462 Please privately send me the availability date of the DDV package,
I have to design a new board and I would use a top thermal paste package.
Thanks

Hi Nakamichi-san,
I just got back to work from my personal travel. Sorry about the delayed response. Let me cite the following snippets from the application note. After a successful learn the ATQ_LRN parameter is determined like you mentioned. This will…
Part Number: DRV8462 Hi TI Support Team
I made some measurement with ATQ_EN=1 and it seams TRQ_DAC seems to be overdriven. I can control Motor Current by TRQ_DAC when ATQ_EN=0. I can not control motor current by TRQ_DAC when ATQ_EN=1.
Is there another way…
Part Number: DRV8462 Champs,
I noticed we added a silent step mode in DRV8462. In this mode we are using a PI controller to achieve a current close loop. This is well aligned with the trend we see in customer side, where they are try to achieve 'servo…
Part Number: DRV8462 Hello,
I have an application where I need to drive two stepper motors. Both are 24V, 2.6A each. Is the DRV8462 a good solution for this? I assume that I will need one part per stepper motor correct?
Also, when is the DRV8462DDV…
