It reports local temperature to ±2°C maximum accuracy and remote temperature to ±1°C maximum accuracy. Communication is over I²C/SMBus. ## Supply range and temperature grade Runs on a 3V to 3.6V rail — common for 3.3V logic domains — and is specified for the full industrial ambient range of -40°C to 125°C. The remote sensor can monitor a hot spot up to 150°C, so it handles the exhaust side of a crowded chassis or a heatsink-mounted power device without the local die seeing that heat directly. ## Package and mounting Supplied in a 16-lead SSOP (3.90 mm body width) or the functionally identical 16-QSOP supplier device package, both surface-mount. Cut Tape is also available for prototype or low-volume builds. ## Lifecycle and compliance Listed as active in production with ROHS3 compliance. There is no last-time-buy or NRND notice on this part, so it remains eligible for new designs and production BOMs without an obsolescence watch.","metaTitle":"MAX6639AEE+T Temperature Monitor, Fan Controller","metaDescription":"MAX6639AEE+T from Analog Devices: dual-channel temp monitor with ±1°C remote accuracy, I²C/SMBus interface, PWM fan control.
