µP Reset Circuits with Long Manual Reset

Setup Period

General Description

Features

The MAX6443–MAX6452 low-current microprocessor

reset circuits feature single or dual manual reset inputs

with an extended 6.72s setup period. Because of the

extended setup period, short switch closures (nuisance

resets) are ignored.

♦ Single- or Dual-Supply Voltage Monitors

♦ Precision Factory-Set Reset Thresholds from

1.6V to 4.6V

♦ Adjustable Threshold to Monitor Voltages Down

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 of 6.72s.

These devices ignore manual reset transitions of less

than 6.72s (typ).

to 0.63V (MAX6449–MAX6452)

♦ Single or Dual Manual Reset Inputs with Extended

6.72s Setup Period

♦ Optional Short Setup Time Manual Reset Input

(MAX6447/MAX6448 and MAX6451/MAX6452)

♦ Immune to Short Voltage Transients

♦ Low 6µA Supply Current

♦ 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.

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

Outputs

♦ 140ms (min) Reset Timeout Period

♦ Small SOT143 and SOT23 Packages

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.

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).

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

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

ber suffix found in Table 1. 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.
