MAX4073T/F/H
Low-Cost, SC70, Voltage-Output,
High-Side Current-Sense Amplifier
General Description
The MAX4073 low-cost, high-side current-sense amplifier features a voltage output that eliminates the need
for gain-setting resistors making it ideal for cell phones,
notebook computers, PDAs, and other systems where
current monitoring is crucial. High-side current monitoring does not interfere with the ground path of the
battery charger making the MAX4073 particularly useful
in battery-powered systems. The input common-mode
range of +2V to +28V is independent of the supply voltage. The MAX4073’s wide 1.8MHz bandwidth makes it
suitable for use inside battery-charger control loops.
The combination of three gain versions and a selectable external-sense resistor sets the full-scale current
reading. The MAX4073 offers a high level of integration, resulting in a simple and compact current-sense
solution.
The MAX4073 operates from a +3V to +28V single supply and draws only 0.5mA of supply current. This
device is specified over the automotive operating temperature range (-40°C to +125°C) and is available in a
space-saving 5-pin SC70 package (half the size of the
SOT23).
For a similar device in a 6-pin SOT23 with a wider common-mode voltage range (0 to +28V), see the
MAX4173 data sheet.

Detailed Description
The MAX4073 high-side current-sense amplifier features a +2V to +28V input common-mode range that is
independent of supply voltage. This feature allows the
monitoring of current out of a battery as low as +2V and
also enables high-side current sensing at voltages
greater than the supply voltage (VCC).
The MAX4073 operates 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 (ILOAD)(RSENSE). Since IRG1 flows through RG1,
IRG1 = (ILOAD)(RSENSE) / RG1. The internal current mirror
multiplies I RG1 by a current gain factor, β, to give
IRGD = β ✕ IRG1. Solving IRGD = β ✕ (ILOAD)(RSENSE)/
RG1. Assuming infinite output impedance, VOUT = (IRGD)
(RGD). Substituting in for IRGD and rearranging, VOUT =
β ✕ (RGD/RG1)(RSENSE ✕ ILOAD). The parts gain equals
β ✕ RGD/RG1. Therefore, V OUT = (GAIN) (R SENSE )
(ILOAD), where GAIN = 20V/V for MAX4073T, GAIN =
50V/V for MAX4073F, and GAIN = 100V/V for MAX4073H.
Set the full-scale output range by selecting RSENSE and
the appropriate gain version of the MAX4073.
Applications Information
Recommended Component Values
The MAX4073 senses a wide variety of currents with
different sense resistor values. Table 1 lists common
resistor values for typical operation of the MAX4073.

higher-sense voltage that reduces offset voltage errors
of the internal op amp. Typical sense voltages range
between 10mV and 150mV.
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 (±5V).
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.
INPUT
0.3in COPPER
For VSENSE = 100mV, full-scale output voltage can be
2V, 5V, or 10V depending on the gain. For proper operation, ensure VCC exceeds the full-scale output voltage
by 1.2V (see Output High Voltage (V CC - V OH ) vs.
Temperature in the Typical Operating Characteristics).
0.1in COPPER
For example, the MAX4073T (with a maximum load current of 10A and an RSENSE of 5mΩ) creates a full-scale
VSENSE of 50mV that yields a maximum VOUT of 1V.
RSENSE in this case requires about 2 inches of 0.1 inchwide copper trace.
Output Impedance
The output of the MAX4073 is a current source driving a
12kΩ resistance. Resistive loading added to OUT
reduces the output gain of the MAX4073. To minimize
output errors for most applications, connect OUT to a
high-impedance input stage. When output buffering is
required, choose an op amp with a common-mode
input range and an output voltage swing that includes
ground when operating with a single supply. The op
amp’s supply voltage range should be at least as high
as any voltage the system may encounter.
The percent error introduced by output loading is determined with the following formula:

Using a PCB Trace as RSENSE
If the cost of RSENSE is an issue and accuracy is not
critical, use the alternative solution shown in Figure 2.
This solution uses copper PC board traces to create a
sense resistor. The resistivity of a 0.1-inch-wide trace of
2-ounce copper is approximately 30mΩ/ft. The resistance-temperature coefficient of copper is fairly high
(approximately 0.4%/°C), so systems that experience a
wide temperature variance must compensate for this
effect. In addition, do not exceed the maximum power
dissipation of the copper trace.
