Temp sensor measures five locations

Sunnyvale, Calif. — Maxim Integrated Products Inc.'s precision five-channel temperature sensor is said to accurately measure its own temperature — and the temperature of up to four external locations with 1°C temperature accuracy.

The four remote locations can be the central processing unit (CPU), graphics processing unit (GPU), memory devices, and other locations important in notebook applications. The MAX6699 also allows the user to program the temperature threshold of alarm outputs. Designed for user flexibility, these outputs can serve as an interrupt, or can be connected to a system fan or other thermal management circuitry.

The combination of high precision, small size, and high flexibility makes the MAX6699 a suitable choice for notebook applications, where accurate temperature readings of multiple locations are a must, according to Maxim.

The MAX6699 communicates through an SMBus interface. It operates from a 3.0-V to 5.0-V supply voltage range and consumes only 500 μA of supply-current, which drops to only 3 μA in standby mode. The MAX6699 is specified over the -40°C to +125°C temperature range.

Prices start at $2.75 each (2,500-up, FOB USA). Click here for the preliminary MAX6699 data sheet.
