3-Pin, Ultra-Low-Power SC70/SOT23
Voltage Detectors
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
Features

Approximately 100mV Increments
? ±2.5% Threshold Accuracy Over Temperature
? Low Cost
? Available in Three Versions: Push-Pull OUT ,
Push-Pull OUT, and Open-Drain OUT

Ordering Information
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

* The
MAX6375/MAX6376/MAX6377 are available in factory-preset
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.

Load Switching/Power Sequencing
Power-Supply Monitoring in Digital/Analog Systems
Portable/Battery-Powered Equipment
thresholds from 2.20V to 3.08V, in approximately 0.1V increments.
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 non-
standard versions (Table 2). Contact factory for availability. All
devices available in tape-and-reel only.
Devices are available in both leaded and lead-free packaging.
Specify lead-free by replacing “-T” with “+T” when ordering.
