This single-supply, low-side, bidirectional, current-sensing solution can accurately detect load currents from –1 A to 1 A. The linear range of the output is from 110 mV to 3.19 V. Low-side current sensing keeps the common-mode voltage near ground, and is thus most useful in applications with large bus voltages.
