The MAX6457–MAX6460 high supply voltage, low-power

voltage monitors operate over a 4V to 28V supply voltage

range. Each device includes a precision bandgap reference,

one or two low-offset voltage comparators, internal threshold

hysteresis, power-good or reset timeout options, and one

or two high-voltage open-drain outputs. Two external

resistors (three for window detection) set the trip threshold

voltages.

The MAX6457 is a single voltage monitor for undervoltage

or overvoltage detection. A logic-based clear input either

latches the output for overvoltage applications or allows

the device to operate in transparent mode. The MAX6458

includes two comparators (one overvoltage and one

undervoltage) for window detection and a single output

to indicate if the monitored input is within an adjustable

voltage window. The MAX6459 includes dual overvoltage/

undervoltage comparators with two independent compar-

ator outputs. Use the MAX6459 as a window comparator

with separate undervoltage and overvoltage outputs or as

two independent, single voltage monitors. The MAX6460

includes a single comparator and an internal reference,

and can also accept an external reference. The inverting

and noninverting inputs of the comparator are externally

accessible to support positive or negative voltage moni-

tors and to configure the device for active-high or active-

low output logic.

The MAX6457/MAX6458 offer fixed timing options as

a voltage detector with a 50μs typical delay or as a

reset circuit with a 90ms minimum reset timeout delay.

The monitored input must be above the adjusted trip

threshold (or within the adjusted voltage window for the

MAX6458) for the selected timeout period before the

output changes state. The MAX6459/MAX6460 offer only

a fixed 50μs timeout period. Internal threshold hysteresis

options (0.5%, 5%, and 8.3% for the MAX6457/MAX6458/

MAX6459, and 0.5% for the MAX6460) reduce output

chatter in noise-sensitive applications. Each device is

available in a small SOT23 package and specified over

the extended temperature range of -40°C to +125°C.

Note:

The MAX6457/MAX6458/MAX6459 are available with

factory-trimmed internal hysteresis options. The MAX6457 and

MAX6458 offer two fixed timing options. Select the desired hys-

teresis and timing options using Table 1 or the Selector Guide

at the end of the data sheet, and enter the corresponding let-

ters and numbers in the part number by replacing “_ _” or “_”.

These devices are offered in tape-and-reel only and must be

ordered in 2500-piece increments.

Devices are available in both leaded and lead(Pb)-free/RoHS

compliant packaging. Specify lead(Pb)-free by replacing “-T”

with “+T” when ordering.
