Single/Dual/Quad High-Side Current-Sense
Amplifiers with Internal Gain
General Description
Features
The MAX4376/MAX4377/MAX4378 single, dual, and
quad precision high-side current-sense amplifiers are
available in space-saving packages. They feature
buffered voltage outputs that eliminate the need for
gain-setting resistors and are ideal for today’s notebook
computers, cell phones, and other systems where cur-
rent monitoring is critical. These precision devices are
offered in three fixed-gain versions of 20, 50, and 100:

High-side current monitoring is especially useful in bat-
tery-powered systems since it does not interfere with
the ground path of the battery charger. The input com-
mon-mode range of 0 to +28V is independent of the
supply voltage and ensures that the current-sense
feedback remains viable even when connected to a
battery pack in deep discharge.

Ordering Information
The full-scale current reading can be set by choosing
the appropriate voltage gain and external-sense resis-
tor. This capability offers a high level of integration and
flexibility, resulting in a simple and compact current-
sense solution.

MAX4376FAUK-T
The MAX4376/MAX4377/MAX4378 operate over a sup-
ply voltage range of +3V to +28V, draw 1mA of supply
current per amplifier, and operate over the full automo-
tive temperature range of -40°C to +125°C. These
devices have a wide bandwidth of 2MHz, making them
suitable for use inside battery-charger control loops.
The buffered outputs drive up to 2mA of output current
into a ground-referenced load.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Detailed Description
The MAX4376/MAX4377/MAX4378 high-side current-
sense aꢀplifiers feature a 0 to +28V input coꢀꢀon-ꢀode
range that is independent of supply voltage. This feature
allows the ꢀonitoring of current out of a battery in deep
discharge and also enables high-side current sensing at
Applications Information
Recommended Component Values
The MAX4376/MAX4377/MAX4378 sense a wide variety
of currents with different sense resistor values. Table 1

The MAX4376/MAX4377/MAX4378 operate as follows:

inverting input has high iꢀpedance, negligible current
flows through RG2 (neglecting the input bias current).
Therefore, the sense aꢀplifier’s inverting-input voltage

Systeꢀs such as laptop coꢀputers and other devices
that have internal charge circuitry require a precise
bidirectional current-sense aꢀplifier to ꢀonitor accu-
rately the battery’s current regardless of polarity. Figure
2 shows the MAX4377 used as a bidirectional current
Therefore:
V
OUT
= (GAIN)(R
)(I
)
SENSE LOAD
where GAIN = 20 for MAX437_T.
GAIN = 50 for MAX437_F.
GAIN = 100 for MAX437_H.
