Analog Devices ADM1171 Hot Swap Controller Datasheet
The ADM1171 hot‑swap controller enables safe insertion and removal of a PCB on a live backplane by using an external N‑channel MOSFET and a current‑sense resistor. It operates from 2.7 V to 16.5 V and includes features such as soft‑start, undervoltage lockout, and a current‑sense output (CSOUT) with a gain of 20.
Two device options are offered: the ADM1171‑1 with automatic retry after an over‑current fault, and the ADM1171‑2 with latch‑off behavior. The device is supplied in an 8‑lead TSOT package and is intended for hot‑swap board insertion in line cards, RAID systems, and industrial high‑side switches.
