DRV8320: Direction control in 1x PWM mode

Part Number: DRV8320

Hi

We use DRV8320H, and assume 1x PWM mode.

The direction of rotation can be controlled by INHC (DIR) from MCU.

Are there any procedure of changing direction while motor spining?

Can we change direction without any consideration ?(motor speed, BEFM and so on)

BestRegards

    Hello na na78,

    For the DRV8320, you should be fine to change direction without consideration to speed and BEMF. If there are any issues, the DRV8320's protection features should shutdown the device before any damage occurs. However, depending on your motor load, you may see better system performance by slowing the motor before changing direction.
