The MAX4374 EV kit is fully assembled and tested.
Follow the steps below to verify the board operation.
Caution: Do not turn on power supply or the elec-
tronic load until all connections are completed.
1) Connect the positive terminal of the 5V supply to
2) Connect the positive terminal of the 12V supply to
3) Set the electronic load to sink 500mA.
4) Connect the electronic load’s positive terminal to
5) Connect the first voltmeter across the OUT and GND
6) Connect the second voltmeter across the COUT2
7) Turn on the power supplies.
8) Turn on the electronic load.
9) Verify that the OUT voltmeter reading is approximately

The MAX4374 evaluation kit (EV kit) provides a proven
design to evaluate the MAX4374 low-cost, micropower,
high-side current-sense supervisor that contains a high-
side current-sense amplifier, bandgap reference, and
comparator with latching output. This EV kit demon-
strates the MAX4374 in a 10-pin µMAX package. The
MAX4374 is also available in 14-pin SO, but that pack-
age is not compatible with this EV kit.
The load current is measured as a voltage drop
(V
age is then amplified by the current-sense amplifier and
presented as a voltage at its output pin (OUT). Like all
differential amplifiers, the output voltage has two com-
ponents of error, an offset error and a gain error. The
offset error affects accuracy at low V
gain error affects accuracy at large V
mizing both offset and gain errors, accuracy can be
optimized over a wide dynamic range.
The MAX4374 EV kit is installed with a MAX4374FEUB+,
which has a gain of 50V/V. The current-sense resistor
