ADM1063 Rev. 0 is a multisupply supervisor/sequencer with ADC and temperature monitoring. It provides a complete supervisory and sequencing solution for up to 10 supplies, enabling supervision with better than 1% accuracy. It also features various input and output functions that can be configured and controlled as needed.
The ADM1063 is a configurable multisupply supervisor and sequencing device that monitors up to ten power supplies, provides programmable fault detection, and integrates a 12‑bit ADC and six 8‑bit DACs for closed‑loop margining. It offers programmable output drivers, temperature sensing, and SMBus control for flexible board power management.
The document includes a functional description, detailed pin‑out tables, absolute maximum ratings, electrical specifications, and guidance for programming the device via EEPROM. It also provides application examples for server, router, and multivoltage system use cases.
