DRV8328: finding issue in the rotation of the motor

Tejas N

Part Number: DRV8328

Tool/software:

We are using a drv8328 gate driver for our 12V BLDC motor rated at 10A max, and we are facing the issue of the rotation of the motor.

Can anyone give us the logic of rotation for the 3-phase BLDC motor?

Hey Tejas,

Thank you for the question. We will aim to provide an update before the end of the week.

Best,

Hi Tejas,

Can you give some more detail around the issue? Is the fault pin latched?

You can find simple logic tables based on the PWM mode selected in the datasheet:

Yes, we have done this. the thing is, the motor rotates little bit like a jerk and stops

Do you have output waveforms?

GHx to SHx, SHx to GND, and GLx to GND? Is there any fault being triggered?
