Temperature Sensor Simplifies Thermal Profiling of Portable Consumer Electronics

Texas Instruments unveiled its TMP103 digital temperature sensor, which consumes 97 percent less power and is 75 percent smaller than the next closest competitor, according to the company. It also provides global read/write functionality to ease thermal profiling. Using a single command, eight TMP103 devices mounted on the board can simultaneously identify and monitor hotspots. The sensor is asserted to simplify thermal profiling while enabling longer battery life and smaller form factors for portable consumer electronics such as smartphones, tablets, laptops and netbooks. The device draws a maximum of 1 uA while in shutdown mode and 3 uA while in active mode to extend battery life. In its active state, it is said to draw approximately half the power of the next closest competitor in shutdown state. The device measures only 0.76 mm x 0.76 mm, making it suitable for high-density, space-constrained applications requiring multiple temperature measurement zones.
