Part Number: DRV8428 Hi team,
issue: The customer designed a drive circuit using the drv8428 stepper motor drive chip, but the motor only vibrates but does not spin when used.
Note: The circuit is designed with reference to a typical application in the…

We have used stepper motor driver IC DRV8884 since long time. It works perfect in production.
We are using stepper motor at 12V / 300mA per winding.
But, unfortunately…
Dong,
Thank you for your post. It looks like you found the problem.

Part Number: DRV8428 Hi,
I am evaluating our board design with DRV8428 on it. We noticed an issue - when the motor trying to rotate sometimes has a high pitch noise. Once the high pitch noise occurred, the motor will not rotate. The noise usually stays…
Part Number: DRV8428 Hi,
My customer evaluates DRV8428 EVM. Unfortunately, the motor current wave form doesn't be pure sin wave as below: It looks like the flat is shown at zero cross point.
And Below is GUI setting:
Could you please give me advice…
Part Number: DRV8428 We are evaluating the DRV8428EPWPR for a consumer product, using the attached schematic.
The issue is when pulsing Step, OUT1 stays at 12V (VM) regardless of DIR/Step.
BOUT pulses as expected.
Any suggestions?
Thank you,
Grant
Part Number: DRV8428 Hi team,
Could you give me comment on following customer questions?
Q1. When the customer wants to set M0/M1 pin as "0", can M0/M1 pin be directly shortened to GND?
Q2. If not on the answer for Q1, and if some pull down…
Part Number: DRV8428 When the DRV8428 is in fast decay mode, the datasheet mentions that the opposite MOSFET's are turned on. I understand from this that the decay current does not circulate through the MOSFET body diodes like in many of other motor drivers…
