Thermal management, the task of creating and maintaining optimal operating conditions for electronic devices, is vital for creating long-lasting, reliable products. This is especially true for System on Chips (SoCs) and high-power processors, where heat dissipation and thermal noise must be considered to prevent damage or malfunction. A good thermal management solution should provide accurate and repeatable temperature control across a wide range of temperatures. The MAX6664AEE+ is an ultra-low-power, high accuracy temperature monitor and fan control IC that offers precise temperature measurement and precise control of thermal management solutions.

The MAX6664AEE+ is a highly integrated to reduce the design complexity. It includes a temperature sensor and high accuracy +/-1°C (typical) temperature-to-digital converter, a temperature range selector, low-current mode control, over-temperature alarm and reset, and Fan-Speed Control. The device can operate over a temperature range of -40°C to +125°C (+150°C with Derating). With its built-in alarm, the MAX6664AEE+ can provide thermal protection for processors, system peripherals and other sensitive components, ensuring their reliability and maximizing their lifespan.

The MAX6664AEE+ supports a wide variety of fan control functions, allowing the users to adjust the fan speed according to their operating conditions. It supports various control modes, such as On/Off, LCA (Load Cell Assist) and PWM (Pulse-Width Modulation) control, making it suitable for a wide range of applications. The fan speed can either be set manually or automatically via one of the temperature range selectors. All fan speed settings can be monitored and adjusted digitally.

The MAX6664AEE+ also features a low-power mode that saves power by switching off the temperature sensor when it is not needed. The device is further optimized to reduce electromagnetic emissions, resulting from fan control, by keeping the output in the “off” state until it is needed. This ensures efficient thermal management and ensures that the environment around the device remains clean and safe from electromagnetic interference.

The MAX6664AEE+ offers outstanding performance and features for temperature monitoring and critical thermal management applications. Its combination of low power consumption, precise temperature measurement and highly configurable fan control makes it an indispensable tool for a variety of applications, such as automotive, industrial, medical, communications and embedded systems.
