Other Parts Discussed in Thread: TPS7B81-Q1
Tool/software:
Hello Team,
We are planning to use the DRV8106-Q1 in our design to drive an inductive load. According to the datasheet, it has an input offset voltage of +/- 3.5 mV at 105°C and a current sense gain error of 2%. Of course, input bias current and Reference voltage (has 1.5% accuracy with TPS7B81-Q1) will also contribute to current sense accuracy.
Given that our load current ranges from 7 A to 30 A, does TI offer any calibration mechanism or recommended approach to compensate or correct for current sense errors?
Thank you,
Rama
