Part Number: DRV8428
Tool/software:
Hi
The customer uses DRV8428, but the stepper motor does not move. The driver output has a waveform AOUT 2 phase delay AOUT 1 180 degrees, BOUT 1 delay AOUT 2 90 degrees, BOUT 2 delay BOUT 1 180 degrees, the motor…
Part Number: DRV8428 Tool/software: We are using a DRV8428RTER on a simple board to drive a small step bipolar motor (winding res: 60ohm) at 12V supply.
Unfortunately we can't get any output to drive the motor windings.
We have tied nSLEEP to VM:…
Part Number: DRV8428 Tool/software: Hi, I'm considering to use 30 pcs DRV8428 in parallel.
1. If the FPGA IO drive capacity is 20mA, is it possible to control (H/L/Hi-Z) the M0/M1 pins of 30 drivers with one FPGA IO pin? M0/M1 will not be changed…
Part Number: DRV8428 Tool/software: Hello, I'm considering to use DRV8428 with supplying 5V at VM.
In that case,
1. What is the voltage of DVDD?
2. If DVDD is not 5V, is it better to use VM 5V and voltage divider to adjust VREF to set IFS?
3.…
Part Number: DRV8428 Tool/software: Hi,
We are considering using separate power supplies for the driver and the external controller.
If the EN pin is pulled up to high when VM is not supplied, is there a possibility of failure, malfunction, or voltage…

This is Ram, We are migrating the motor driver from DRV8825 to DRV8428, We worked on the DRV8428EVM, But we made a separate PCB for the DRV8428…
Part Number: DRV8428 Tool/software: Hello -
I would like to use the DRV8428P to drive two single coil latching relays (Coil 1 between AOUT1 and AOUT2, Coil 2 between BOUT1 and BOUT2).
The coils will be pulsed for ~50-100mS pulses every couple of minutes…
Part Number: DRV8428 hi team,
do we have any limitation on the variation of STEP control signal? as this is driven by MCU GPIO, there may be variation on the control frequency which is not fully aligned with setting frequency.
so my customer want…
