MAX691 Datasheet Microprocessor Supervisory Circuits

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX690–MAX695 Microprocessor Supervisory Circuits General.

General Description

The MAX690 family of supervisory circuits reduces the plexity and number of ponents required for power supply monitoring and battery control functions in microprocessor systems.

These include µP reset and backup-battery switchover, watchdog timer, CMOS RAM write protection, and power-failure warning.

The MAX690 family significantly improves system reliability and accuracy pared to that obtainable with separate ICs or discrete ponents.

Key Features

  • Supervisory Function Integration Saves Board Space while Fully Protecting Microprocessor-Based Systems.
  • Precision Voltage Monitor -- 4.65V (MAX690, MAX691, MAX694, MAX695) -- 4.40V (MAX692, MAX693).
  • Power OK/Reset Time Delay -- 50ms, 200ms, or Adjustable.
  • Watchdog Timer -- 100ms, 1.6s, or Adjustable.
  • Battery Backup Power Switching.
  • Voltage Monitor for Power Fail or Low Battery Warning.
  • Minimum External Component Count.
