Abstract:
A system includes a motor and a motor controller coupled to the motor. The motor controller includes a current sense circuit configured to: receive a first phase current sense measurement on a first measurement path; receive the first phase current sense measurement on a second measurement path; receive a second phase current measurement on the first measurement path; receive the second phase current on the second measurement path; average the first phase current sense measurement on the first measurement path with the first phase current sense measurement on the second path; and average the second phase current sense measurement on the first measurement path with the second phase current sense measurement on the second path.
