MAX805L - Microprocessor Supervisory Circuits

Download the MAX805L datasheet PDF. This datasheet also covers the MAX692A variant, as both devices belong to the same microprocessor supervisory circuits family and are provided as variant models within a single manufacturer datasheet.

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.
