3-Pin, Ultra-Low-Power SC70/SOT23
Voltage Detectors
General Description
Features
The MAX6375–MAX6380 are ultra-low-power circuits
used for monitoring battery, power-supply, and regulat-
ed system voltages. Each detector contains a precision
bandgap reference, comparator, and internally trimmed
resistors that set specified trip threshold voltages.
These devices provide excellent circuit reliability and
low cost by eliminating external components and
adjustments when monitoring nominal system voltages
from 2.5V to 5V.
o Ultra-Low 500nA Supply Current
(MAX6375/MAX6376/MAX6377)
o Thresholds Available from 2.20V to 4.63V in
Approximately 100mV Increments
o
2.5% Threshold Accuracy Over Temperature
o Low Cost
o Available in Three Versions: Push-Pull OUT,
Push-Pull OUT, and Open-Drain OUT

MAX6377 have voltage thresholds between 2.20V and
3.08V in approximately 100mV increments. The
MAX6378/MAX6379/MAX6380 have voltage thresholds
between 3.30V and 4.63V in approximately 100mV
increments.
*
The MAX6375/MAX6376/MAX6377 are available in factory-pre-
set thresholds from 2.20V to 3.08V, in approximately 0.1V incre-
ments. The MAX6378/MAX6379/MAX6380 are available in
factory-preset thresholds from 3.30V to 4.63V, in approximately
0.1V increments. Choose the desired threshold suffix from
Table 1 and insert it in the blank spaces following R. There are
21 standard versions, with a required order increment of 2500
pieces. Sample stock is generally held on the standard versions
only (see the Selector Guide). The required order increment is
10,000 pieces for nonstandard versions (Table 2). Contact facto-
ry for availability. All devices available in tape-and-reel only.
Ultra-low supply current of 500nA (MAX6375/MAX6376/
MAX6377) makes these parts ideal for use in portable
equipment. All six devices are available in a space-sav-
ing SC70 package or in a tiny SOT23 package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

The MAX6375/MAX6376/MAX6377 are available in factory-pre-
set thresholds from 2.20V to 3.08V, in approximately 0.1V incre-
ments. The MAX6378/MAX6379/MAX6380 are available in
factory-preset thresholds from 3.30V to 4.63V, in approximately
0.1V increments. Choose the desired threshold suffix from Table
1 and insert it in the blank spaces following R. There are 21 stan-
dard versions, with a required order increment of 2500 pieces.
Sample stock is generally held on the standard versions only
(see the Selector Guide). The required order increment is 10,000
pieces for nonstandard versions (Table 2). Contact factory for
availability. All devices available in tape-and-reel only.
