MAX802M - Microprocessor Supervisory Circuits

This page provides the datasheet information for the MAX802M, a member of the MAX692A Microprocessor Supervisory Circuits family.

Description

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

They significantly improve system reliability and accuracy compared to separate ICs or discrete components.

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.

MAX690A/MAX692A/ MAX802L/MAX802M/ MAX805L Microprocessor Supervisory Circuits General Description The MAX690A/MAX692A/MAX802L/MAX802M/MAX805L reduce the complexity and number of components required for power-supply monitoring and batterycontrol functions in microprocessor (μP) systems. They significantly improve system reliability and accuracy compared to separate ICs or discrete components. These parts provide four functions: 1) A reset output during power-up, power-down, and brownout conditions. 2) Battery-backup switching for CMOS RAM, CMOS μP, or other low-power logic. 3) A reset pulse if the optional watchdog timer has not been toggled within 1.6s. 4) A 1.25V threshold detector for power-fail warning or low-battery detection, or to monitor a power supply other than +5V.
