DRV8316-Q1: The location and direction of current sensing

Part Number: DRV8316-Q1

Hi, 

■ Question 1
Which is SOX detecting, current path A or current path B?
Both can be grasped from the data sheet, so I would like to confirm it just in case.

■ Question 2
Regarding Question 1, is it okay to recognize that ± of the SoX voltage conversion formula is determined by the direction of the current?

Thanks,

Astro

    Hi Astro,

    Thanks for reaching out!

    SOx is detecting current path B.

    That is correct. Figure 8-28 in the data sheet shows the SOx output voltage corresponding to the positive or negative IoutX input. 

    Let me know if my response has resolved your questions!
