µP Reset Circuits with Long Manual Reset

Setup Period

3–MAX6452

General Description

Features

o Single- or Dual-Supply Voltage Monitors

o Precision Factory-Set Reset Thresholds from

The MAX6443–MAX6452 low-current microprocessor

reset circuits feature single or dual manual reset inputs

with an extended setup period. Because of the extend-

ed setup period, short switch closures (nuisance resets)

are ignored.

1.6V to 4.6V

o Adjustable Threshold to Monitor Voltages Down

to 0.63V (MAX6449–MAX6452)

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.

o Single or Dual Manual Reset Inputs with Extended

Setup Period

o Optional Short Setup Time Manual Reset Input

(MAX6447/MAX6448 and MAX6451/MAX6452)

o Immune to Short Voltage Transients

o Low 6µA Supply Current

o Guaranteed Valid Reset Down to V

= 1.0V

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.

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

Outputs

o 140ms (min) Reset Timeout Period

o Small SOT143 and SOT23 Packages

Ordering Information

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.

Note: The first “_ _ ” is a placeholder for the threshold voltage

level of the devices. A desired threshold level is set by the two-

number suffix found in Table 1. The third "_" is a placeholder

for the manual reset setup period of the devices. A desired

setup period is set by the letter suffix found in Table 2. All

devices are available in tape-and-reel only. There is a 2500-

piece minimum order increment for standard versions (Table

2). Sample stock is typically held on standard versions only.

Nonstandard versions require a minimum order increment of

10,000 pieces. Contact factory for availability.

The MAX6443–MAX6452 have an active-low RESET

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

devices, offered in small SOT packages, are fully guar-

anteed over the extended temperature range (-40°C to

+85°C).
