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

until V

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.

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.
