It integrates an ADC, comparator, fan speed counter, multiplexer, and register bank on-chip, and communicates over an SMBus interface. Typical applications include server racks, telecom enclosures, and industrial equipment where closed-loop fan speed control keeps component temperatures within the -40°C to 120°C external sensor range. ## ±1.5°C accuracy — what it means for thermal management The ±1.5°C maximum accuracy on the internal and external temperature channels is tight enough to set aggressive fan-speed ramps without false triggers. A ±2°C part like the ADT7468ARQ-REEL7 forces wider guard bands, reducing the thermal headroom for the system. For a server or base-station design that needs to push airflow only when the junction actually rises, the ADT7463ARQ-REEL7's tighter spec saves fan power and acoustic noise. ## Lifecycle and compliance note The ADT7463ARQ-REEL7 is listed as Active with no end-of-life notice. However, it is RoHS non-compliant, which restricts its use in EU and many other markets unless an exemption applies. For designs that require RoHS compliance, consider the functionally similar ADT7463ARQ (same die, different reel suffix) or the ADT7468ARQ-REEL7 which carries a ±2°C accuracy spec.","metaTitle":"ADT7463ARQ-REEL7 Fan Control, Temp Monitor, ±1.5°C, SMBus","metaDescription":"ADI ADT7463ARQ-REEL7 fan controller and temperature monitor with ±1.5°C accuracy, SMBus output, 3V to 5.5V supply, 24-QSOP package.
