The MAX6884/MAX6885 EEPROM-configurable, multivoltage power-supply supervisors monitor six voltage-detector 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 active-low RESET, active-low UV/active-low OV, and active-low WDO provide system resets/interrupts. Programmable output options include open-drain or weak pullup. Programmable timing delay blocks configure each output to wait between 25µs and 1600ms after their respective assertion-causing conditions have been cleared. A fault register logs condition-causing events (undervoltage, overvoltage, manual reset, etc.).An internal 10-bit, 1% accurate ADC (MAX6884 only) converts the voltages at IN1–IN6, AUXIN, and VCCthrough a multiplexer that automatically sequences through all inputs every 200ms. An SMBus™/I²C-compatible serial data interface programs and communicates with the configuration EEPROM, configuration registers, internal 512-bit user EEPROM, and reads the ADC registers (MAX6884 only) and fault registers.The MAX6884/MAX6885 are available in a 5mm x 5mm x 0.8mm 20-pin thin QFN package and operate over the extended temperature range (-40°C to +85°C).ApplicationsMultimicroprocessor/Voltage SystemsNetworking SystemsServers and WorkstationsStorage EquipmentTelecommunication/Central Office SystemsWireless Base Stations
