MAX6754–MAX6764 Low-Power, Single/Dual-Voltage Window Detectors

General Description

The MAX6754–MAX6764 low-power window detec-

tors monitor undervoltage/overvoltage conditions on

system power supplies. These devices assert when the

monitored voltage is under the undervoltage and/or over

the overvoltage thresholds.

The MAX6754–MAX6759/MAX6763/MAX6764 monitor

a single voltage. The MAX6760/MAX6761/MAX6762

monitor dual-voltage systems. The MAX6754/MAX6755/

MAX6756 provide a single undervoltage/overvoltage

output and the MAX6757–MAX6764 provide independent

undervoltage and overvoltage outputs. The outputs are

available in push-pull or open-drain configurations.

The MAX6754–MAX6762 offer factory-fixed voltage

thresholds for monitoring system voltages from 0.9V to

5V with a selectable ±5%, ±10%, or ±15% window voltage.

The MAX6763/MAX6764 allow for externally adjustable

thresholds. The MAX6754–MAX6762 are available in

two delay-timing options (20μs, typ or 100ms, min). The

MAX6760/MAX6761/MAX6762 also include a latched

overvoltage output function and the MAX6754–MAX6762

include a manual reset input.

This family of products is available in small SOT23 and

TDFN packages, and is specified over the extended

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