Low-Voltage SOT23 µP Supervisors with

Manual Reset and Watchdog Timer

General Description

Features

The MAX6821–MAX6825 are low-voltage microprocessor

(µP) supervisory circuits that combine voltage monitor-

ing, watchdog timer, and manual reset input functions in

a 5-pin SOT23 package. Microprocessor supervisory cir-

cuits significantly improve system reliability and accura-

cy compared to separate ICs or discrete components.

These devices assert a reset signal whenever the moni-

tored voltage drops below its preset threshold, keeping it

o Monitors +1.8V, +2.5V, +3.0V, +3.3V, +5.0V

Supplies

o 140ms (min) Reset Timeout Delay

o 1.6s Watchdog Timeout Period

(MAX6821/MAX6822/MAX6823/MAX6824)

o Manual Reset Input

(MAX6821/MAX6822/MAX6823/MAX6825)

o Three Reset Output Options

asserted for a minimum timeout period after V

rises

above the threshold. In addition, a watchdog timer moni-

tors against code execution errors. A debounced manual

reset is also available. The MAX6821–MAX6825 monitor

voltages from +1.8V to +5.0V. These outputs are guaran-

Push-Pull RESET

Open-Drain RESET

teed to be in the correct state for V

down to +1.0V.

o Guaranteed Reset Valid to V

o Immune to Short Negative V

o No External Components

= +1.0V

Nine preprogrammed reset threshold voltages are

available (see Threshold Suffix Guide). The MAX6821,

MAX6822, and MAX6823 all have a manual reset input

and a watchdog timer. The MAX6821 has push-pull

RESET, the MAX6822 has open-drain RESET, and the

MAX6823 has push-pull RESET. The MAX6824 has a

watchdog timer and both push-pull RESET and push-

pull RESET. The MAX6825 has a manual reset input

and both push-pull RESET and push-pull RESET. The

Selector Guide explains the functions offered in this

series of parts.
