Analog Devices ADM1186 Quad Voltage Sequencer and Monitor Handbook
The ADM1186‑1 and ADM1186‑2 are integrated four‑channel voltage monitoring and sequencing devices that operate from a 2.7 V to 5.5 V supply. They provide programmable up‑ and down‑sequencing, open‑drain enable outputs, a power‑good output, and a fault pin for safe power‑rail management.
The document includes functional descriptions, pin configurations, timing diagrams, absolute maximum ratings, and detailed electrical specifications for both the 20‑lead QSOP (ADM1186‑1) and 16‑lead QSOP (ADM1186‑2) packages.
