Regarding the current sense output of Pololu G2 High-Power Motor Driver 18v17:
is it ratiometric? That is, does it vary with Vin, the input voltage? My guess: no, because the schematic appears to show the current sense is the output of an op amp arranged as a differential amplifier, and that shouldn’t vary with Vcc or Vin…
Hello.
I edited your post to remove references to components that we generally do not disclose.
The current sense output on our G2 High-Power Motor Drivers is not ratiometric (i.e. it is not affected by the input voltage).

Gotcha. Thank you.
