MAX6884 - Hex Power-Supply Supervisory Circuits

Description

The MAX6884/MAX6885 EEPROM-configurable, multivoltage power-supply supervisors monitor six voltagedetector inputs, one auxiliary input, and one watchdog input, and feature three programmable outputs for highly configurable power-supply monitoring applications.

Features

  • 6 Configurable Input Voltage Detectors Programmable Thresholds 0.5V to 3.05V (in 10mV Increments) or 1V to 5.8V (in 20mV Increments) Primary UV and Secondary UV/OV Thresholds.
  • One Configurable Watchdog Timer from 6.25ms to 102.4s.
  • Configurable RESET, UV/OV, and WDO Outputs.
  • Three Programmable Outputs Open-Drain or Weak Pullup RESET, UV/OV, and WDO Active-Low Output Logic Timing Delays from 25µs to 1600ms.
  • Margining Disable and Manual Reset Controls.

MAX6884/MAX6885 19-3594; Rev 0; 2/05 EVAALVUAAILTAIOBNLEKIT EEPROM-Programmable, Hex Power-Supply Supervisory Circuits General Description The MAX6884/MAX6885 EEPROM-configurable, multivoltage power-supply supervisors monitor six voltagedetector inputs, one auxiliary input, and one watchdog input, and feature three programmable outputs for highly configurable power-supply monitoring applications. Manual reset and margin disable inputs offer additional flexibility. Each voltage-detector input offers a programmable primary undervoltage and secondary undervoltage/overvoltage threshold. Voltage-detector inputs IN1–IN6 monitor voltages from 1V to 5.8V in 20mV increments or 0.5V to 3.05V in 10mV increments. Programmable outputs RESET, UV/OV, and WDO provide system resets/interrupts.
