DRV8323: Direction of current in shunt reverses

Hi Team,

My customer came to me with some questions on our DRV8323HRTAR for their design.
They found that the direction of the current in the shunt resistor reverses with each positive edge of the three Hall signals. This behavior does not occur with the negative edge:

They are using the DRV8323HRTAR with the 1xPWM mode.

Can you help me to understand this behavior? Are they doing something wrong? How can they solve this problem?

Thanks!

BR,

Alfred
