MAX6443–MAX6452

µP Reset Circuits with Long Manual Reset

Setup Period

General Description

Features

● Single or Dual-Supply Voltage Monitors

The MAX6443–MAX6452 low-current microprocessor

reset circuits feature single or dual manual reset inputs

with an extended setup period. Because of the extended

setup period, short switch closures (nuisance resets) are

ignored.

● Precision Factory-Set Reset Thresholds from

1.6V to 4.6V

● Adjustable Threshold to Monitor Voltages Down to

0.63V (MAX6449–MAX6452)

● Single or Dual Manual Reset Inputs with Extended

Setup Period

● Optional Short Setup Time Manual Reset Input

(MAX6447/MAX6448 and MAX6451/MAX6452)

● Immune to Short Voltage Transients

● Low 6µA Supply Current

On all devices, the reset output asserts when any of

the monitored supply voltages drops below its specified

threshold. The reset output remains asserted for the reset

timeout period (210ms typ) after all monitored supplies

exceed their reset thresholds. The reset output is one-

shot pulse asserted for the reset timeout period (140ms

min) when selected manual reset input(s) are held low for

an extended setup timeout period. These devices ignore

manual reset transitions of less than the extended setup

timeout period.

● Guaranteed Valid Reset Down to V

= 1.0V

● Active-Low RESET (Push-Pull or Open-Drain)

Outputs

● 140ms (min) Reset Timeout Period

● Small SOT143 and SOT23 Packages

● AEC-Q100 Qualified (MAX6444US16K/V+T)

The MAX6443–MAX6448 are single fixed-voltage µP

supervisors. The MAX6443/MAX6444 have a single

extended manual reset input. The MAX6445/MAX6446

have two extended manual reset inputs. The MAX6447/

MAX6448 have one extended and one immediate manual

reset input.

Ordering Information at end of data sheet.

The MAX6449–MAX6452 have one fixed-threshold µP

supervisor and one adjustable-threshold µP supervisor.

The MAX6449/MAX6450 have two delayed manual reset

inputs. The MAX6451/MAX6452 have one delayed and

one immediate manual reset input.

Typical Operating Circuit

+3.3V

The MAX6443–MAX6452 have an active-low RESET with

push-pull or open-drain output logic options. These devic-

es, offered in small SOT packages, are fully guaranteed

over the extended temperature range (-40°C to +85°C).
