MAX6889, MAX6890, MAX6891 EEPROM-Programmable, Octal/Hex/Quad, Power-Supply Sequencers/Supervisors

The MAX6889 MAX6890 MAX6891 EEPROM-configurable, multivoltage supply Sequencers supervisors monitor several voltage detector inputs and generalpurpose Logic inputs and feature programmable outputs for highly configurable power-supply sequencing applications. The MAX6889 features eight voltage detector inputs and ten programmable outputs. The MAX6890 features six voltage detector inputs and eight programmable outputs, while the MAX6891 features four voltage detector inputs and five programmable outputs. Manual reset and margin disable inputs offer additional flexibility. All voltage detectors offer a configurable threshold for undervoltage detection. High-Voltage input IN1 monitors voltages from 2.5V to 13.2V in 50mV increments, or from 1.25V to 7.625V in 25mV increments. Inputs IN2-IN7 monitor voltages from 1V to 5.5V in 20mV increments or from 0.5V to 3.05V in 10mV increments. High-Voltage input IN8 monitors voltages from 2.5V to 15.25V in 50mV increments, or from 1.25V to 7.625V in 25mV increments. Programmable output stages control power-supply sequencing or system resets/interrupts. Programmable output options include: active-high, active-low, open drain, and weak pullup. Programmable Timing delay blocks configure each output to wait between 25s and 1600ms before deasserting. The MAX6889 MAX6890 MAX6891 feature a watchdog Timer for added flexibility. Program the watchdog Timer to assert one or more programmable outputs. The initial and normal watchdog timeout periods are independently programmable from 6.25ms to 102.4s. An SMBus IC-compatible, 2-wire serial data Interface programs and communicates with the configuration EEPROM the configuration Registers and the internal 512-bit user EEPROM The MAX6889 MAX6890 MAX6891 are available in 5mm x 5mm x 0.8mm thin QFN packages and are specified to operate over the extended temperature range (-40C to +85C).
