The MAX6639AEE+ from Maxim Integrated is a high-precision, dual-channel temperature sensor designed for a wide range of applications, including computers, servers, data storage systems, and other electronic devices that require thermal monitoring. This advanced sensor is capable of monitoring its own temperature as well as the temperature of a remote thermal diode, which can be located on a CPU, GPU, or other heat-generating components.

Key Features

• Accuracy: The MAX6639AEE+ offers exceptional accuracy, with a local temperature sensing accuracy of ±1°C and a remote temperature sensing accuracy of ±3°C over a temperature range of -40°C to +125°C.
• Dual Channels: It features two temperature measurement channels – one for the local sensor and one for a remote thermal diode-connected sensor.
• Programmable Limits: Users can set programmable overtemperature alarms for both channels, enabling proactive system thermal management.
• Communication Interface: The device communicates over a 2-wire SMBus/I²C-compatible serial interface, making it easy to integrate into most digital systems.
• Adjustable Hysteresis: It includes programmable hysteresis and a fault queue to help prevent false tripping of the alarm signal.
• Supply Voltage: The sensor operates from a single 3.0V to 3.6V power supply, which is typical for most logic circuits.
• Package: Housed in a compact 16-pin QSOP package, the MAX6639AEE+ is designed for space-constrained applications.
