TIPD156
Low-Drift Bidirectional Single-Supply Low-Side Current Sensing Reference Design
TIPD156
Overview
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.
