Part Number: DRV8434E Hello expert,
When I use smart tune ripple control (XDECAY=1), how should I configurate the Toff?
In the DS, it shows the " The TOFF pin configures the PWM OFF time for all decay modes except smart tune ripple control". Is that…

Hello Sir:
Our customer is using ROHM BD62221MUV and Allegro A5995.
Can we recommend DRV8434E to replace ROHM BD62221MUV and Allegro A5995?
If it cannot be, would you please provide recommendations…
Part Number: DRV8434E Other Parts Discussed in Thread: DRV8847 , DRV8434 , INA181 , DRV8876 , DRV8231A Hi,
I plan to drive two small DC motors with the DRV8434E (or DRV8434P). These have internal current sensing for chopping control, but unfortunately do…
Part Number: DRV8434E Other Parts Discussed in Thread: DRV8434 Hi team,
I have questions on DRV8434E’s Smart tune Ripple Control. Could you please take a look?
Q1: In Ripple Control mode, I believe TOFF would not affect the control algorism. Is…

My customer wants to select a motor driver that could both support "BDC" and "Stepper", and gave the preliminary spec requirements…
Hey Shuji,
David has done some bench testing and just needs to write up the response.
Is this a new design? The DRV8881 is a very old device, I highly recommend looking at a newer device instead such as DRV8434E . It is cheaper, higher current, smaller…
Hi Higa san,
Thank you for your question.
Normally we recommend DRV8434E which is newer generation device for stepping motor family. It has smart tune ripple control which is new method to reduce ripple.
However, if customer use 1% external resistor,…
Part Number: DRV8434PEVM Other Parts Discussed in Thread: MSP-FET , DRV8434 , DRV8434E I bought the DRV8434PEVM evaluation board... I would like to use the the driver with STEP/DIR so on the evaluation board I removed the R6 for the interface. I use the…
Hey Thaisa,
If you're only using 2 pairs of coils ON at a time I agree with using the table as a reference. Doing that then it would probably be easiest to use 1 stepper motor driver that supports microstepping and then use an array of FETS/relays…
Part Number: DRV8434EEVM Other Parts Discussed in Thread: DRV8434E , DRV8434 Hi team,
Could you share the thickness of DRV8434EEVM’s each layer?
I would like to know the best layout/board setting for thermal dissipation for DRV8434E.
I found similar…
