关于DRV8873的反馈电压。

看芯片手册看到IPROPI1和IPROPI2

IPROPI1
High-side FET current. The analog current proportional to the current flowing
in the half bridge.
IPROPI2
High-side FET current. The analog current proportional to the current flowing
in the half bridge.

注释都是约 1 / 1100 的电流转化为电压,AD采集

请问两路反馈有什么区别吗?是否采集一路就可以?
