MAX6870 Overview
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.
Key Features
- programmable outputs for highly configurable power-supply sequencing applications
- Manual reset and margin disable inputs offer additional flexibility
- All voltage detectors offer two configurable thresholds for undervoltage/overvoltage or dual undervoltage detection
- 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 before deasserting
- A fault register logs the condition that caused each output to assert (undervoltage, overvoltage, manual reset, etc.)
