High-Side Power and
Current Monitors
The MAX4210/MAX4211 low-cost, low-power, high-side
power/current monitors provide an analog output voltage proportional to the power consumed by a load by
multiplying load current and source voltage. The
MAX4210/MAX4211 measure load current by using a
high-side current-sense amplifier, making them especially useful in battery-powered systems by not interfering with the ground path of the load.
The MAX4210 is a small, simple 6-pin power monitor
intended for limited board space applications. The
MAX4210A/B/C integrate an internal 25:1 resistor-divider
network to reduce component count. The MAX4210D/E/F
use an external resistor-divider network for greater design
flexibility.
The MAX4211 is a full-featured current and power monitor. The device combines a high-side current-sense
amplifier, 1.21V bandgap reference, and two comparators with open-drain outputs to make detector circuits
for overpower, overcurrent, and/or overvoltage conditions. The open-drain outputs can be connected to
potentials as high as 28V, suitable for driving high-side
switches for circuit-breaker applications.
Both the MAX4210/MAX4211 feature three different current-sense amplifier gain options: 16.67V/V, 25.00V/V, and
40.96V/V. The MAX4210 is available in 3mm x 3mm, 6-pin
TDFN and 8-pin µMAX® packages and the MAX4211 is
available in 4mm x 4mm, 16-pin thin QFN and 16-pin
TSSOP packages. Both parts are specified for the -40°C
to +85°C extended operating temperature range.

*FSO refers to full-scale output under the conditions: VSENSE = 100mV, VRS+ = +25V, or VIN = 1V.
All devices are 100% production tested at TA = +25°C. All temperature limits are guaranteed by design.
Guaranteed by power-supply rejection test.
Guaranteed by output voltage error tests (IOUT).
Guaranteed by output voltage error tests (IOUT or POUT, or both).
IN Input Voltage Range (MAX421_D/E/F) and VRS+ Input Voltage Range (MAX421_A/B/C) are guaranteed by design
(GBD) and not production tested. See Multiplier Transfer Characteristics graphs in the Typical Operating Characteristics.
Note 6: This test does not apply to the low gain options, MAX421_A/D, because OUT is clamped at approximately 4V.
Note 7: The device does not experience phase reversal when overdriven.
Note 8: VPULLUP is defined as an externally applied voltage through a resistor, RPULLUP, to pull up the comparator output.
Note 9: POUT gain accuracy is the sum of gain error and multiplier nonlinearity.
Note 10: Total output voltage error is the sum of gain and offset voltage errors.
Note 11: POUT Output Offset Voltage is the sum of offset and multiplier feedthrough.

Detailed Description
The MAX4210/MAX4211 families of current- and powermonitoring ICs integrate a precision current-sense
amplifier and an analog multiplier for a variety of current and power measurements. The MAX4211 integrates an additional uncommitted 1.21V reference and
two comparators with open-drain outputs. These features enable the design of detector circuits for overpower, overcurrent, overvoltage, or any combination of
fault conditions. The MAX4210/MAX4211 offer various
gains, packages, and configurations allowing for
greater design flexibility and lower overall cost.
These devices monitor the load current with their highside current-sense amplifiers and provide an analog
GND
output voltage proportional to that current at IOUT
(MAX4211). This voltage is fed to the analog multiplier
for multiplying the load current with a source voltage to
obtain a voltage proportional to load power at POUT.
Current-Sense Amplifier
The integrated current-sense amplifier is a differential
amplifier that amplifies the voltage across RS+ and RS-.
A sense resistor, RSENSE, is connected across RS+
and RS-. A voltage drop across RSENSE is developed
when a load current is passed through it. This voltage
is amplified and is proportional to the load current. This
voltage is also fed to the analog multiplier for powersensing applications (see the Analog Multiplier section). The current-sense amplifiers feature three gain
options: 16.67V/V, 25.0V/V, and 40.96V/V (see Table 1).

MAX4210/MAX4211
Functional Diagrams (continued)
MAX4210/MAX4211
High-Side Power and
Current Monitors
The common-mode voltage range is +4V to +28V and
independent of the supply voltage. With this feature, the
device can monitor the output current of a high-voltage
source while running at a lower system voltage typically
between 2.7V and 5.5V.
The MAX4211 has a current-sense amplifier output. The
voltage at IOUT is proportional to the voltage across
VSENSE:
VIOUT = AVIOUT x VSENSE
where VSENSE is the voltage across RS+ and RS-, and
AVIOUT is the amplifier gain of the device given in Table 1.
Analog Multiplier
The MAX4210/MAX4211 integrate an analog multiplier
that enables real-time monitoring of power delivered to
a load. The voltage proportional to the load current is
fed to one input of the multiplier and a voltage proportional to the source voltage is fed to the other. The analog multiplier multiplies these two voltages to obtain an
output voltage proportional to the load power. The analog multiplier is designed only to operate in the positive
quadrant, that is, the inputs and outputs are always
positive voltages.
For the MAX4210D/E/F and MAX4211D/E/F, the analog
multiplier full-scale input at IN is approximately 1V. This
independent multiplier input allows greater design flexibility when using an external voltage-divider. For the
MAX4210A/B/C and MAX4211A/B/C, an integrated voltage-divider divides the source voltage at the RS+ pin
by a nominal value of 25 and passes this voltage to the
multiplier. Thus, the full-scale input voltage at RS+ is
25V. The integrated, trimmed resistor-dividers reduce
external component count and cost.
The voltage output at POUT is proportional to the output
power:
For the MAX4210A/B/C and MAX4211A/B/C:
VPOUT = AVPOUT x VSENSE x VRS+
For the MAX4210D/E/F and MAX4211D/E/F:
VPOUT = AVPOUT x VSENSE x VIN
Table 1. MAX4211 Current-Sense
Amplifier Gain and Full-Scale Sense
Voltage
where VSENSE is the voltage across RS+ and RS- and
A VPOUT is the amplifier gain of the device given in
Table 2.
Internal Comparators (MAX4211)
The MAX4211 features two uncommitted open-drain
output comparators. These comparators can be configured to trip when load current or power reaches a set
limit. They can also be configured as a window comparator with wire-OR output. Comparator 1 (COUT1)
features latch-enable (LE) and inhibit (INHIBIT) inputs.
When LE is low, the comparator is transparent (it functions as a regular unlatched comparator). When LE is
high, the comparator output (COUT1) is latched. When
high, the INHIBIT input suspends the comparator operation and latches the output to the current state. The
operation of INHIBIT is similar to LE, except it has a different input threshold and wider hysteresis. The INHIBIT logic-high threshold is 1.21V and logic-low threshold
is 0.6V with 0.6V hysteresis. INHIBIT is useful in preventing the comparator from giving false output during
fast RS+ transients. INHIBIT is generally triggered by
an RC network connected to RS+ (see the Applications
Information). Both comparators have a built-in 300µs
blanking period at power-up to prevent false outputs.
The comparator outputs are open drain and they can
be pulled up to VCC, RS+, or any voltage less than
+28V. LE and INHIBIT are internally pulled down by a
1µA source.

Applications Information
Recommended Component Values
Ideally, the maximum load current develops the fullscale sense voltage across the current-sense resistor.
Choose the gain version needed to yield the maximum
current-sense amplifier output voltage without saturating it. The typical high-side saturation voltage is about
VCC - 0.25V. The current-sense amplifier output voltage
is given by:
VIOUT = VSENSE x AVIOUT
where VIOUT is the voltage fed to the analog multiplier
or at IOUT. VSENSE is the sense voltage. AVIOUT is the
current-sense amplifier gain of the device specified in
Table 1. Calculate the maximum value for RSENSE so
the differential voltage across RS+ and RS- does not
exceed the full-scale sense voltage:
RSENSE =
VSENSE(FULL−SCALE)
ILOAD(FULL−SCALE)
Choose the highest value resistance possible to maximize VSENSE and thus minimize total output error. In
applications monitoring high current, ensure that
RSENSE is able to dissipate its own I2R power dissipation. If the resistor’s power dissipation is exceeded, its
value can drift or it can fail altogether, causing a differential voltage across the terminals in excess of the
absolute maximum ratings. Use resistors specified for
current-sensing applications.
Window Comparator
In some applications where undercurrent or underpower (open-circuit fault) and overcurrent or overpower
(short-circuit fault) needs to be monitored, a window
comparator is desirable. Figure 1 shows a simple circuit
suitable for window detection. Let POVER be the minimum load power required to cause a low state at
COUT2, and let PUNDER be the maximum load current
required to cause a high state at COUT1:
PUNDER (WATTS) =
POVER (WATTS) =
⎛ R1 + R2 ⎞
VREF
⎟
AVPOUT × RSENSE ⎜⎝
R2
⎠
⎛ R4 + R5 ⎞
VREF
⎟
AVPOUT × RSENSE ⎜⎝
R5
⎠
where AVPOUT is the power-sense amplifier gain given
in Table 2, and VREF is the internal reference voltage
(1.2V, typ). The resulting comparator output is high
22
when the current is inside the current window and low
when the current is outside the window. Note that
COUT1 and COUT2 are wire-ORed together.
Overpower Circuit Breaker
Figure 2 shows a circuit breaker that shuts off current to
the load when an overpower fault is detected (the same
circuit can be used to detect overcurrent conditions by
connecting the R1-R2 resistor-divider to IOUT, instead
of POUT). This circuit is useful for protecting the battery
from short-circuit or overpower conditions. When a
power fault is detected, the P-MOSFET, M1, is turned
off and stays off until the manual reset button is
pressed. Also, cycling the input power causes the LE
pin to go low, which unlatches the comparator output
OUT1 and resets the circuit breaker.
During power-up or when the characteristics of the load
change, there can be an inrush current into the load. The
temporary inrush current results in a higher voltage at
POUT. This can bring the voltage at CIN+ above the reference voltage at CIN-, and, as a result, COUT1 goes
high triggering the circuit-breaker function. This unwanted
behavior can be disabled by bringing comparator 1’s
INHIBIT input high. An RC network connected to INHIBIT
(R4 and C1) can be incorporated to suspend comparator
1’s operation for a brief period. In this way, short surges in
load power can be made invisible to the circuit-breaker
function, while longer term overpower load demands (or a
load short circuit) still “trip the breaker.”
The logic-high threshold for INHIBIT is typically 1.2V,
and the logic-low threshold is 0.6V. During power-up,
INHIBIT quickly exceeds 1.2V through C1 and inhibits
COUT1 from changing state. The comparator inputs are
“inhibited” until the INHIBIT voltage is discharged to
0.6V. R3 is a current-limiting resistor, typically 10kΩ,
which protects the INHIBIT input. Since INHIBIT is a
high-impedance input, R3 has no effect on the R4-C4
charge/discharge time. The time during which the comparator is suspended is approximated by:
⎛ ∆V ⎞
tINHIBIT = R4 × C1 In ⎜
⎟
⎝ 0.6V ⎠
where ∆V is the voltage change at the load. For
improved transient immunity, tINHIBIT can be increased
as required, with the understanding that the breaker
function will be suspended for this period.
If any comparator is not used, its input must be biased
to a known state. For example, connect CIN+ to VCC
and CIN- to GND.

Variable-Gain Amplifier
Figure 3 shows single-ended input, variable-gain amplifiers (VGA). This VGA features more than 200kHz bandwidth and is useful in automatic gain-control circuits
commonly found in baseband processors. The gain is
controlled by applying 0 to 1V to IN (V GC ) of the
MAX4210D/E/F; 0V corresponds to minimum gain and
1V corresponds to maximum gain.
Measure Load Power
The MAX4210A/B/C and MAX4211A/B/C have internal
voltage-divider resistors connected to RS+ and the
analog multiplier input. This configuration measures
source power accurately and provides protection to the
power source such as a battery. To measure the load
power accurately, choose the MAX4210D/E/F and
MAX4211D/E/F with an external resistor-divider connected directly to the load as shown in Figure 4. This
configuration improves the load-power measurement
accuracy by excluding the additional power dissipated
by RSENSE.
Power-Supply Bypassing
Bypass VCC to GND with a 0.1µF ceramic capacitor to
isolate the IC from supply-voltage transients. To prevent high-frequency coupling, bypass RS+ or RS- with
a 0.1µF capacitor. On the TDFN and thin QFN packages, there is an exposed paddle that does not carry
any current, but should also be connected to the
ground plane for rated power dissipation.
