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

Figure 31. Bidirectional Current Sensing

For applications requiring a bidirectional current measurement,

an optimal solution can be using a single channel device, which

offers the same functionality as the previous circuit. The AD8210

is a single channel current sensor featuring bidirectional capability.

The typical connection diagram for the AD8210 in bidirectional

applications is shown in Figure 32.
