The auto-retry feature (the '-1' variant) automatically attempts to restart after a fault, which is useful for transient loads or hot-swap cards that must self-recover without a system reset. ## Package and mounting — TSOT-23-8 for compact layouts Housed in a TSOT-23-8 package (also listed as SOT-23-8 Thin), this is a surface-mount part intended for reflow assembly. The small footprint suits dense PCB layouts where board area is at a premium — typical for add-in cards, blade servers, or multi-rail power management sections. The supplier device package is TSOT-23-8. ## Lifecycle and compliance — active, ROHS3, no obsolescence concern ADI lists the ADM1172-1AUJZ-RL7 as Active with a ROHS3 compliance rating. For BOM planning, this part can be specified into new designs without an immediate end-of-life risk.","metaTitle":"ADM1172-1AUJZ-RL7 Hot Swap Controller, I²C, TSOT-23-8","metaDescription":"ADI ADM1172-1AUJZ-RL7 hot swap controller with I²C, UVLO, auto retry. 2.7V-16.5V supply, 650 µA quiescent, -40°C to 85°C.

Both share the same pinout, package, and programmable features, so they are footprint-compatible. Choose the variant based on whether your system needs automatic recovery (auto retry) or prefers a latched fault for diagnostic clarity."},{"question":"Is ADM1172-1AUJZ-RL7 compatible with 3.3V logic?","answer":"Yes, the I²C interface operates from the same 2.7V to 16.5V supply rail, so it is directly compatible with 3.3V logic levels without additional level shifting."},{"question":"How do I program the current limit on ADM1172-1AUJZ-RL7?","answer":"The current limit is set by selecting an external sense resistor value between the VCC and SENSE pins. The controller regulates the voltage across this resistor to a typical 26 mV threshold. Refer to the datasheet for the resistor calculation formula based on your desired load current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADM1172-1AUJZ-RL7","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADM1172-1AUJZ-RL7 when reusing this data.
