Analog Devices ADM1185 Quad Voltage Monitor and Sequencer Datasheet
The ADM1185 integrates four precision comparators to monitor separate voltage rails and a digital core that provides sequencing and fault protection. It operates from a 2.7 V to 5.5 V supply, offers three open‑drain enable outputs (OUT1‑OUT3) and a common power‑good output (PWRGD), and is packaged in a 10‑lead MSOP.
Typical applications include power‑supply monitoring, power‑up sequencing for telecom and data‑communication equipment, and PCs/servers. The device features programmable voltage thresholds via external resistor dividers, internal timing delays for controlled start‑up, and robust protection against over‑voltage and undervoltage conditions.
