1µA, 4-Bump UCSP/SOT23,
Precision Current-Sense Amplifier
Battery-powered systems may require a precise bidi-
rectional current-sense amplifier to accurately monitor
the battery’s charge and discharge currents.
Measurements of the two separate outputs with respect
to GND yields an accurate measure of the charge and
discharge currents, respectively (Figure 1).
