TYPICAL APPLICATIO
N
U
Bidirectional Current Sensor
A bidirectional current sensor for battery-powered sys-
tems is shown in Figure 3. Two outputs are provided: one
proportional to charge current, the other proportional to
discharge current. The circuit takes advantage of the
LT1498’s rail-to-rail input range and its output phase
reversal protection. During the charge cycle, the op amp
A1 forces a voltage equal to (I
L
)(R
SENSE
) across R
A
. This
voltage is then amplified at the Charge Out by the ratio of
R
B
over R
A
. In this mode, the output of A2 remains high,
keeping Q2 off and the Discharge Out low, even though the
(+) input of A2 exceeds the positive power supply. During
the discharge cycle, A2 and Q2 are active and the operation
is similar to the charge cycle.
