Detailed Description
The MAX4210/MAX4211 families of current- and power-
monitoring ICs integrate a precision current-sense
amplifier and an analog multiplier for a variety of cur-
rent and power measurements. The MAX4211 inte-
grates an additional uncommitted 1.21V reference and
two comparators with open-drain outputs. These fea-
tures enable the design of detector circuits for over-
power, 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 high-
side current-sense amplifiers and provide an analog

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, R SENSE , is connected across RS+
and RS-. A voltage drop across R SENSE 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 power-
sensing applications (see the Analog Multiplier sec-
tion). The current-sense amplifiers feature three gain
options: 16.67V/V, 25.0V/V, and 40.96V/V (see Table 1).
