The ADM1166 is a super sequencer with margining control and nonvolatile fault recording. It contains 10 supply fault detectors that allow supervision of supplies to <0.5% accuracy at all voltages at 25°C, <1.0% accuracy across all voltages and temperatures. 16 event deep black box nonvolatile fault recording allows the sequencer to record supply voltages, currents, temperatures, fault events and fault codes.
The ADM1166 Super Sequencer® is a configurable supervisory and sequencing device for up to ten supplies. It integrates a 12‑bit ADC, six 8‑bit DACs, a 16‑event deep non‑volatile fault recorder, and ten programmable driver outputs that can drive logic or high‑voltage gates.
The device operates via an industry‑standard SMBus interface, offers programmable input attenuation, and includes a 256‑byte user EEPROM for configuration storage. Detailed specifications, pin descriptions, and timing diagrams are provided for hardware designers.
