This document introduces the features and characteristics of Analog Devices ADM1178 hot swap controller and digital power monitor.
The ADM1178 provides safe board insertion and removal from a live backplane by controlling supply voltages from 3.15 V to 16.5 V. It includes a precision current‑sense amplifier, a 12‑bit ADC, and an I²C fast‑mode‑compliant interface for reading voltage and current data. The device drives an external N‑channel FET and offers programmable hot‑swap timing, over‑current protection, and an ALERTB interrupt output.
Typical applications include power monitoring and budgeting in central office equipment, telecommunications hardware, and PCs/servers. The datasheet details functional block diagrams, pin configurations, electrical specifications, thermal characteristics, and timing diagrams for I²C communication.
