Analog Devices ADM1170 Hot Swap Controller Datasheet
The Analog Devices ADM1170 is a hot swap controller designed to allow circuit boards to be safely inserted into or removed from a live backplane. It achieves this by controlling the inrush current of supply bypass capacitors using an external N-channel FET, preventing damage to connector pins and system glitches.
The device operates with a supply voltage ranging from 2.7V to 16.5V but can control voltages down to 0.6V via separate SENSE pins. It features true soft start for inrush current profiling, an adjustable analog current limit acting as a circuit breaker, and automatic retry or latch-off functionality depending on the specific model variant.

Questions answered in these manuals
What is the function of the ADM1170?
It is a Hot Swap controller that allows a board to be safely inserted and removed from a live backplane.
How does the device handle overcurrent conditions?
It limits current by reducing the gate voltage of an external FET, with automatic retry or latch-off depending on the model.
What is the purpose of the ADM1170?
The ADM1170 is a hot‑swap controller that safely enables a printed‑circuit board to be removed and inserted to a live backplane.
How many variants of the ADM1170 are available?
Two options are offered: the ADM1170‑1 with automatic retry for over‑current faults and the ADM1170‑2 with latch‑off for an over‑current fault.
What supply voltage range does the ADM1170 support?
The ADM1170 operates from 2.7 V up to 16.5 V.
What is the function of the ON (ON‑CLR) pin?
The ON (ON‑CLR) pin enables the device, can reset a latched fault, and acts as a comparator input with a 1.3 V threshold.
