That means the host controller must poll the register bank over SMBus to read temperature and fan speed; the part does not assert a hardware interrupt. If your design relies on an alert pin to trigger a fan-fail response, this part requires a firmware workaround or an external comparator. ## Lifecycle and sourcing posture The ADT7468ARQZ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"ADT7468ARQZ dBCool® Fan Controller, ±2°C Accuracy","metaDescription":"ADI ADT7468ARQZ dBCool® fan control & temp monitor, ±2°C max accuracy, SMBus output, 3V-5.5V supply, 24-QSOP.

This is the worst-case error across the full temperature range, not a typical value — design your thermal thresholds with that ±2°C guard band in mind."},{"question":"Does ADT7468ARQZ work with 3.3V SMBus or only 5V?","answer":"The supply voltage range is 3V to 5.5V, so the part operates on both 3.3V and 5V SMBus rails directly. No external level shifter is needed."},{"question":"When sourcing ADT7468ARQZ, what is the closest functional alternate?","answer":"The ADT7468ARQZ-RL7 and ADT7468ARQZ-REEL are tape-and-reel packaging variants of the same die and function — identical specs, same ±2°C accuracy, same SMBus interface. The ADT7468ARQ-REEL7 is a functionally identical part from the same series but in a different reel quantity. All share the same 24-QSOP footprint and active lifecycle. For dual-sourcing, any of these can serve as a drop-in replacement on the BOM, provided the packaging format (tube vs reel) matches your assembly line."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/ADT7468ARQZ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/ADT7468ARQZ when reusing this data.
