Analog Devices ADM1070 -48 V Hot Swap Controller Datasheet
The ADM1070 is a negative voltage hot swap controller designed to allow a board to be safely inserted and removed from a live -48 V backplane. It achieves this by providing robust current limiting, protection against transient and nontransient short circuits, and overvoltage and undervoltage conditions. The device typically operates from a negative voltage of up to -80 V and can tolerate transient voltages of up to -200 V.

What voltage range does the ADM1070 support?
It typically operates from –36 V to –80 V and can tolerate transient voltages up to –200 V.
How many consecutive auto‑restarts are allowed before the device shuts down?
The controller allows up to seven consecutive auto‑restarts; after that it latches and shuts down.
