Part Number: DRV8425 Other Parts Discussed in Thread: DRV8424 Hi team,
Limit of VREF are different DRV8424 and 5.
Does this mean that the rated current is different for 2.5A and 2.0A, but the internal circuitry of VREF is the same?
Also, if used beyond…

Hi Team,
Can you please help us regarding the issue with DRV8425 in our customer's board? Here is the issue according to our customer.
According to my best knowledge the DRV8425 is implemented in the circuit according to datasheet…
Part Number: DRV8425 Hi Team,
We are planning to add this 0.25 ohm resistor as shown below in series to the PGND, and were wondering if the internal current sense resistor (shown by the arrow) could be effected by it?
Thanks!

Part Number: DRV8425 Other Parts Discussed in Thread: DRV8424EVM Hi team,
Does TI have EVM for DRV8425?
Or, is it supposed to be evaluated with modified DRV8424EVM?

Part Number: DRV8425 Hi all Would you mind if we ask DRV8425? <Question> There is the description. We think nSleep pin's absoulte maximum rating is less than 5.75V. Is this value correct? Kind regards, Hirotaka Matsumoto
Hey Aanchal,
You are correct, VTRIP is always 150mV ±10mV for DRV8847. So yes, agreed, you would select a R_SENSE value to appropriately limit the current.
If this is a new design I recommend looking at a newer motor driver, such as DRV8425 where…
Hey Christopher,
As long as orders continue to come in (which they will), the part will not be End of Life within the next 10 years. We are supporting 20+ years old parts regularly.
Gotcha, unfortunately we don't have many unipolar-specific motor drivers…
