MAX6874, MAX6875 EEPROM-Programmable, Hex/Quad, Power-Supply Sequencers/Supervisors

The MAX6874 MAX6875 EEPROM-configurable, multivoltage supply Sequencers supervisors monitor several voltage detector inputs and general-purpose Logic inputs, and provide programmable open-drain outputs for highly configurable power-supply sequencing applications. The MAX6874 provides six voltage monitor inputs, four general-purpose inputs, and eight programmable open-drain outputs. The MAX6875 provides four voltage monitor inputs, three general-purpose inputs, and five programmable open-drain outputs. Manual reset and margin disable inputs provide additional flexibility. All voltage detectors offer configurable thresholds for undervoltage detection. One High-Voltage input (IN1) provides detector threshold voltages from +2.5V to +13.2V in 50mV increments, or from +1.25V to +7.625V in 25mV increments. A second positive input (IN2) provides detector threshold voltages from +2.5V to +5.5V in 50mV increments, or from +1.25V to +3.05V in 25mV increments. Positive inputs (IN3-IN6) provide detector threshold voltages from +1V to +5.5V in 20mV increments, or from +0.5V to +3.05V in 10mV increments. Programmable output stages control power-supply sequencing or system resets/interrupts. Program the open-drain outputs as active-high or active-low. Programmable Timing delay blocks configure each output to wait between 25s and 1600ms before deasserting. An SMBus IC-compatible serial data Interface programs and communicates with the configuration EEPROM the configuration Registers and the internal 4kb user EEPROM of the MAX6874 MAX6875. The MAX6874 MAX6875 are available in a 7mm x 7mm x 0.8mm, 32-pin TQFN package and operate over the extended temperature range (-40C to +85C).
