Single/Dual/Quad, High-Side Current-Sense
Amplifiers with Internal Gain
General Description
Features
o Low-Cost, Single/Dual/Quad, High-Side Current-
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:
Sense Amplifiers
o ±±.ꢀ5 Typical Full-Scale Accuracy
o +3V to +28V Supply Operation
o Adjustable Current-Sense Capability with External
Sense Resistor
o Buffered Output Voltage with 2mA Drive
o 1mA (typ) Supply Current
o 2.±MHz Bandwidth (Gain = +2±V/V)
o Automotive Temperature Range (-4±°C to +12ꢀ°C)
o High Accuracy +2V to +28V Common-Mode
Range, Functional Down to ±V, Independent of
Supply Voltage

For example, MAX4376TAUK is a single high-side
amplifier with a gain of 20.
o Three Gain Versions Available
+2±V/V (MAX437_T)
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.
+ꢀ±V/V (MAX437_F)
+1±±V/V (MAX437_H)
o Available in Space-Saving ꢀ-Pin SOT23 (Single),
8-Pin µMAX (Dual), and 14-Pin TSSOP (Quad)
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.

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.

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

CC
Choosing R
SENSE
The MAX4376/MAX4377/MAX4378 operate as follows:
To measure lower currents more accurately, use a high
value for R . The high value develops a higher
current from the source flows through R
to the
SENSE
SENSE
load (Figure 1). Since the internal sense amplifier’s
inverting input has high impedance, negligible current
flows through RG2 (neglecting the input bias current).
Therefore, the sense amplifier’s inverting-input voltage

internal op amp.
In applications monitoring very high currents, R

must be able to dissipate the I R losses. If the resistor’s
rated power dissipation is exceeded, its value may drift
or it may fail altogether, causing a differential voltage
across the terminals in excess of the absolute maxi-
mum ratings.

The amplifier’s open-loop gain forces its noninverting
input to the same voltage as the inverting input.
Therefore, the drop across RG1 equals (I

Bidirectional Current-Sense Amplifier
Systems such as laptop computers and other devices
that have internal charge circuitry require a precise
bidirectional current-sense amplifier to monitor accu-

monitor. This is useful for implementing either smart
battery packs or fuel gauges.
