MAX690A Datasheet Microprocessor Supervisory Circuits

Manufacturer: Maxim Integrated (now Analog Devices)

Overview: MAX690A/MAX692A/ MAX802L/MAX802M/ MAX805L Microprocessor Supervisory Circuits.

General Description

The MAX690A/MAX692A/MAX802L/MAX802M/MAX805L reduce the plexity and number of ponents required for power-supply monitoring and batterycontrol functions in microprocessor (μP) systems.

They significantly improve system reliability and accuracy pared to separate ICs or discrete ponents.

These parts provide four functions: 1) A reset output during power-up, power-down, and brownout conditions.

Key Features

  • Precision Supply Voltage Monitor: 4.65V for MAX690A/MAX802L/MAX805L 4.40V for MAX692A/MAX802M.
  • Reset Time Delay: 200ms.
  • Watchdog Timer: 1.6s Timeout.
  • Battery-Backup Power Switching.
  • 200μA Quiescent Supply Current.
  • 50nA Quiescent Supply Current in BatteryBackup Mode.
  • Voltage Monitor for Power-Fail or Low-Battery Warning.
  • Power-Fail Accuracy Guaranteed to ±2% (MAX802L/M).
  • Guaranteed RESET Assertion to VC.
