ADM1069 Rev. C is a Super Sequencer with Margining Control that provides a complete supervisory and sequencing solution for up to 8 supplies.
The ADM1069 Super Sequencer provides a single‑chip solution for monitoring and sequencing up to eight power supplies. It includes a 12‑bit ADC, four 8‑bit voltage‑output DACs, and a 256‑byte EEPROM for configuration storage. The device can be programmed via SMBus and supports both open‑collector and push‑pull output drivers.
Typical applications include central office systems, server and router power cards, multivoltage line cards, and in‑circuit testing of margin‑adjusted supplies. The part is offered in 32‑lead LOFP and 40‑lead LFCSP packages and meets RoHS compliance.
