What this hot swap controller does
The Analog Devices ADM4210-1AUJZ-RL7 is a single-channel hot swap controller in a TSOT-6 package. It operates from 2.7 V to 16.5 V and draws 650 µA of supply current. Key programmable features include current limit, fault timeout, and turn-on voltage, giving you control over the ramp profile and the fault response. The UVLO (undervoltage lockout) ensures the controller stays off until the input rail is stable, preventing partial-power glitches during insertion. The -1 variant implements auto-retry: after a fault timeout, the controller automatically attempts to restart, which suits systems where a temporary overload is expected to clear on its own.
The part is ROHS3 compliant.
