MAX6855 Datasheet Nanopower Up Supervisory Circuits

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: 19-3139; Rev 2; 9/04 Nanopower µP Supervisory Circuits with Manual Reset and Watchdog.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The MAX6854/MAX6855/MAX6856/MAX6858/MAX6860– MAX6869 ultra-low-current (170nA, typ) microprocessor (µP) supervisory circuits bine voltage monitoring, watchdog timer, and manual reset input functions in a 5pin SOT23 package.

These devices assert a reset signal whenever the monitored voltage drops below the factorytrimmed reset threshold voltage, manual reset is asserted, or the watchdog timer expires.

The reset output remains asserted for a minimum timeout period after VCC rises above the reset threshold and manual reset is deasserted.

Key Features

  • Ultra-Low 170nA (typ) Supply Current.
  • Reset Thresholds from +1.575V to +4.625V in Approximately 100mV Increments.
  • Six Minimum Reset Timeout Period Options from 10ms to 1200ms.
  • Manual Reset Option.
  • Watchdog Timer Option.
  • Pin-Selectable 10ms/150ms (min) Reset Timeout Period (MAX6861/MAX6862/MAX6863).
  • Immune to Short VCC Transients.
  • Guaranteed Reset Valid to VCC = +1.1V.
  • Three Reset Output Options: Push-Pull RESET Pus.
