Ultra-Low-Power Voltage Detectors and
μP Supervisory Circuits
General Description
The MAX6461–MAX6466 family of ultra-low-power voltage
detectors and μP reset supervisory circuits monitors bat-
tery, power-supply, and system voltages. Each circuit
includes a precision bandgap reference, a comparator,
internally trimmed resistor networks that set specified trip
thresholds, and an internal 5% threshold hysteresis circuit
(see the Functional Diagram ). Output is asserted when
V CC falls below the internal V TH- and remains asserted
until V CC rises above V TH + (V TH + = V TH - × 1.05). These
devices provide excellent circuit reliability and low cost
by eliminating external components and adjustments
when monitoring nominal system voltages from +1.6V to
+5.5V. The MAX6461/MAX6462/MAX6463 are voltage
detectors with a propagation delay of 17μs.
The MAX6464/MAX6465/MAX6466 are μP supervisory
circuits with a minimum reset timeout period of 150ms. All
devices are available with thresholds from +1.6V to +5.5V
in 100mV increments.
Features
? Ultra-Low 1.0μA Supply Current
? Preset Thresholds from +1.6V to +5.5V in 100mV
Increments
? Internal 5% Threshold Hysteresis
? ±2.5% Threshold Accuracy Over Temperature
? Internal Timeout Period Option (150ms min)
? Immune to Short Voltage Transients
? No External Components
? Available in Three Output Options: Push-Pull
(Active Low/Active High) and Open Drain (Active
Low)
? Fully Specified from -40°C to +125°C
? Small SC70 and SOT23 Packages
Ordering Information
The family is available with three output stage options:
push-pull with active-low output, push-pull with active-
high output, and open drain with active-low output. These
devices are available in SC70 and SOT23 packages
specified over the -40°C to +125°C temperature range.

The MAX6461–MAX6466 are available in factory-set thresholds
from 1.6V to 5.5V in approximately 100mV increments. Choose
the desired voltage threshold suffix from Table 1 and insert it in
the blank spaces in the part number. There are 30 standard ver-
sions with a required order increment of 2500 pieces. Sample
stock generally is held on the standard versions only (Table 2).
Nonstandard versions require a 10k-piece order increment.
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.
