DRV8702-Q1: Current closed loop

Sherry Liang said:

Can our device support hardware current closed loop? If so, what is the accuracy?

Please see following section in the datasheet.

7.3.4 Current Regulation

Vio and Av tolerance are given in the datasheet electrical characteristics section.  Also contributing to error is the external shunt resistor.

Please see section 7.3.5.

Again, Vio, Av and external shunt tolerance contribute to error on SO.  SO can be used to externally close the loop on current.
