Low-Drift Bidirectional Single-Supply Low-Side Current Sensing Reference Design
Description
This Verified TI Precision Design implements a low-drift: bi-directional: low-side: single-supply current sensing solution that measures load currents from -2.5 A to +2.5 A. The output range is from 250 mV to 2.75 V: with 0 A current centered at 1.5 V. To achieve low-drift performance: the solution utilizes the INA213B and REF2030. The design’s functionality and performance were verified by fabricating a PCB and measuring results over temperature from -40 °C to 125 °C.
