MAX6604 temperature sensor from Maxim

Maxim Integrated Products has introduced a small and low-cost temperature sensor designed for thermal monitoring in DDR memory modules. The MAX6604 temperature sensor accurately measures temperature (1C), converts the information to digital format and makes it available over an I?C-compatible interface.

The device continuously monitors the temperature and updates the temperature data eight times per second. This method enhances processing performance by providing a highly accurate reading of the module temperature. Competitive techniques that use temperature sensors on motherboards and guard bands to estimate memory module temperature are much less accurate, the company said.

Offered in tiny TDFN and TSSOP packages, the temperature sensor also includes three address inputs which allow up to eight addresses for this device. The combination of these features makes the MAX6604 suitable choice in high-performance memory modules for notebook computers.

The MAX6604 temperature sensor operates from -20C to 125C and works from a 3-5.5V supply voltage range. Prices start at 95 cents.
