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 current monitoring is critical. These precision devices are
offered in three fixed-gain versions of 20, 50, and 100:

For example, MAX4376TAUK is a single high-side
amplifier with a gain of 20.
High-side current monitoring is especially useful in battery-powered systems since it does not interfere with
the ground path of the battery charger. The input common-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.
The full-scale current reading can be set by choosing
the appropriate voltage gain and external-sense resistor. This capability offers a high level of integration and
flexibility, resulting in a simple and compact currentsense solution.
The MAX4376/MAX4377/MAX4378 operate over a supply voltage range of +3V to +28V, draw 1mA of supply
current per amplifier, and operate over the full automotive 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.
The MAX4376 is available in a tiny 5-pin SOT23 package. The MAX4377/MAX4378 are available in spacesaving 8-pin µMAX ® and 14-pin TSSOP packages,
respectively.

Single/Dual/Quad, High-Side Current-Sense
Amplifiers with Internal Gain
Detailed Description
The MAX4376/MAX4377/MAX4378 high-side currentsense 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
voltages greater than the supply voltage (VCC).
The MAX4376/MAX4377/MAX4378 operate as follows:
current from the source flows through RSENSE to the
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
equals VSOURCE - (ILOAD)(RSENSE).
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 LOAD )
(R SENSE ). Since I RG1 flows through RG1, I RG1 =
(ILOAD)(RSENSE)/RG1. The internal current mirror multiplies IRG1 by a current gain factor, β, to give IRGD = β x
I RG1 . Solving I RGD = β x (I LOAD )(R SENSE )/RG1.
Therefore:
VOUT = β x (RGD/RG1)(RSENSE x ILOAD) x amp gain
where amp gain is 2, 5, or 10.
The part’s gain equals (β x RGD / RG1) x amp gain.
Therefore:
VOUT = (GAIN)(RSENSE)(ILOAD)
where GAIN = 20 for MAX437_T.
GAIN = 50 for MAX437_F.
GAIN = 100 for MAX437_H.
Set the full-scale output range by selecting RSENSE and
the appropriate gain version of the MAX4376/
MAX4377/MAX4378.

Applications Information
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
MAX4376/MAX4377/MAX4378.
Choosing RSENSE
To measure lower currents more accurately, use a high
value for RSENSE. The high value develops a higher
sense voltage that reduces offset voltage errors of the
internal op amp.
In applications monitoring very high currents, RSENSE
must be able to dissipate the I2R 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 maximum ratings.
If ISENSE has a large high-frequency component, minimize the inductance of RSENSE. Wire-wound resistors
have the highest inductance, metal-film resistors are
somewhat better, and low-inductance metal-film resistors are best suited for these applications.
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 accurately the battery’s current regardless of polarity. Figure
2 shows the MAX4377 used as a bidirectional current
monitor. This is useful for implementing either smart
battery packs or fuel gauges.
Current Source Circuit
Figure 3 shows a block diagram using the MAX4376
with a switching regulator to make a current source.
