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 operating temperature range of -40°C to 85°C covers industrial environments — think base-station line cards, industrial PLC racks, and server backplanes where the ambient inside the enclosure can climb well above room temperature.
Lifecycle and sourcing reality
The ADM4210-1AUJZ-RL7 carries an active lifecycle status, so there is no end-of-life risk for ongoing production or new designs. The part is ROHS3 compliant. Sourcing is straightforward through independent distribution: we quote to order against an RFQ, with current availability and pricing confirmed at quote time.
