Current Sensing Resolution on Dual G2 Motor Driver

I doubt it is possible but thought I’d ask. Is it possible to adjust the current sensor resolution on the G2 dual motor driver? my application only draws 2 amps max and the CS jumps in increments of 244ma.



Unfortunately there is not a practical way to change the sensitivity of the current sense feedback on our G2 High-Power Motor Drivers. If you need to measure the current with more resolution, you might consider using a separate current sensor you can place in-line with your motor that has a narrower range, like our ACS714 Current Sensor Carrier -5A to +5A.

By the way, I am not sure what you mean when you say, “the CS jumps in increments of 244ma”. The current sense output sensitivity is approximately 10 mV/A for the 18v22 and 20 mV/A for all other versions. If you think the results from your setup are significantly different from that you are welcome to post which specific board you have along with more details about your system and I can let you know if any problems stand out.
