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 ILOAD and

Channel 2 monitors ICHARGE.

Figure 31. Bidirectional Current Sensing

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

AD8210 is a single channel current sensor featuring bidirec-

tional capability. The typical connection diagram for the

AD8210 in bidirectional applications is shown in Figure 32.
