Shunt Current Sensing Evaluator

Design Summary

Design needs review

The electrical result is usable, but one or more implementation checks should be reviewed.

Equivalent shunt resistance 0.500 mΩ 2 x 1.000 mΩ

Peak shunt voltage 50.0 mV At peak current

Power per shunt 0.90 W 30.0% of single-device rating

Current resolution 80.6 mA/LSB 12-bit ADC at full-scale

Verify loss, device loading, and equal-sharing assumptions for the selected shunt bank.

Equivalent shunt resistance0.500 mΩ

Peak shunt voltage50.0 mV

Total continuous loss1.80 W

Power per shunt0.90 W

Continuous current per shunt30.0 A

Peak current per shunt50.0 A

Assumes equal current sharing across parallel shunts.

Check amplifier output swing, ADC range usage, and current represented by one ADC count.
