Other Parts Discussed in Thread: DRV8885

Hello,

Our customer uses the DRV8885, confuse a little.

In the case of P12 on the datasheet,

the OUT1 connect to (+)terminal of the coil.

In the case of P27 Fig.25 on the datasheet,

the OUT1 connect to (-)terminal of the coil.

I think the P12 is correct. Is this correct?

Hi Naoki,

The (+) (-) mark of coils are only a named reference of motor itself. Change one coil's (+)(-) only makes the motor running at different direction.
There is no connection between the device and the marks. So just ignore it.

Hi Wilson,

Thank you for your fast reply.
I will tell him 'Connect to the coil as you want the direction of the motor running'.

Thanks,
