General Description
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.
These circuits perform a single function: they assert an
output signal whenever the V
CC
supply voltage falls
below a preset threshold. The devices are differentiated
by their output logic configurations and preset thresh-
old voltages. The MAX6375/MAX6378 (push-pull) and
MAX6377/MAX6380 (open-drain) have an active-low
output (
OUT
is logic low when V
CC
is below V
TH
). The
MAX6376/MAX6379 have an active-high push-pull out-
put (OUT is logic high when V
CC
is below V
TH
). All
parts are guaranteed to be in the correct output logic
state for V
CC
down to 1V. The detector is designed to
ignore fast transients on V
CC
. The MAX6375/MAX6376/
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.
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.

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.
