MAX6871

19-3384; Rev 1; 9/04 EEPROM-Programmable Hex/Quad Power-Supply Sequencers/Supervisors with ADC General Description The MAX6870/MAX6871 EEPROM-configurable, multivoltage supply sequencers/supervisors monitor several voltage detector inputs, two auxiliary inputs, and four general-purpose logic inputs. The MAX6870/MAX6871 feature programmable outputs for highly configurable power-supply sequencing applications. The MAX6870 features six voltage detector inputs and eight programmable outputs, while the MAX6871 features four voltage detector inputs and five programmable outputs. Manual reset and margin disable inputs offer additional flexibility. All voltage detectors offer two configurable thresholds for undervoltage/overvoltage or dual 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 bipolar input (IN2) provides detector threshold voltages from ±2.5V to ±15.25V in 50mV increments, or from ±1.25V to ±7.625V 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. Programmable output options include: active-high, active-low, opendrain, weak pullup, push-pull, and charge pump. Programmable timing delay blocks configure each output to wait between 25µs and 1600ms ...
