BIDIRECTIONAL CURRENT SENSING
The AD8213 can also be configured to sense current in both
directions at the inputs. This configuration is useful in charge/
discharge applications. A typical connection diagram is shown
in Figure 31. In this mode Channel 1 monitors I
Channel 2 monitors I
For applications requiring a bidirectional current measurement,
an optimal solution could be to use a single channel device,
which offers the same functionality as the previous circuit. The
