MAX6450 - uP Reset Circuits

Download the MAX6450 datasheet PDF. This datasheet also covers the MAX6443 variant, as both devices belong to the same up reset circuits family and are provided as variant models within a single manufacturer datasheet.

Description

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.

Features

  • o Single- or Dual-Supply Voltage Monitors o Precision Factory-Set Reset Thresholds from 1.6V to 4.6V o Adjustable Threshold to Monitor Voltages Down to 0.63V (MAX6449.
  • MAX6452) o Single or Dual Manual Reset Inputs with Extended 6.72s 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 VCC = 1.0V o Active-Low RESET (Push-Pull or Open-Drain) Outputs o.

19-2656; Rev 1; 1/03 µP Reset Circuits with Long Manual Reset Setup Period General Description 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. 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.
