BIDIRECTIONAL CURRENT SENSING
The AD8212 is a unidirectional current sensing device.
Therefore, in power management applications where both the
charge and load currents must be monitored, two devices can
be used and connected as shown in Figure 27. In this case,
V
OUT
1 increases as I
LOAD
flows through the shunt resistor. V
OUT
2
increases when I
CHARGE
flows through the input shunt resistor.
