The Analog Devices ADM1172-2AUJZ-RL7 is a hot swap controller IC designed to enable safe insertion and removal of printed circuit boards to a live backplane. It controls supply rails ranging from 2.7 V to 16.5 V, providing protected operation.
Key features include adjustable current limit via an external sense resistor, peak fault current limiting with fast response, and a charge-pump gate drive for an external N-FET switch. This device incorporates a power-fail comparator and offers automatic retry or latch-off functionality during current faults. It also includes undervoltage lockout (UVLO).
The ADM1172-2AUJZ-RL7 is suitable for general-purpose applications and is packaged in an 8-lead TSOT-23-8 surface-mount package. Its operating temperature range is -40°C to 85°C.
This controller is ideal for systems requiring robust power management during hot-swapping events, such as line cards and RAID systems, as well as industrial high-side switches and electronic circuit breakers.
