General Description

The MAX6874/MAX6875 EEPROM-configurable, multi voltage 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.
