The SMBus output is the only communication path — there is no PWM tachometer output or standalone alarm pin. 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.

Frequently asked questions
What is the ADT7468ARQZ temperature sensor accuracy?
The ADT7468ARQZ has a maximum accuracy of ±2°C. 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.
Does ADT7468ARQZ work with 3.3V SMBus or only 5V?
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.
When sourcing ADT7468ARQZ, what is the closest functional alternate?
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.
