TI Introduces Smallest Local Digital Temperature Sensor for Thermal Management and Thermal Protection

Posted on: Friday, 21 September 2007, 09:00 CDT

DALLAS, Sept. 21 /PRNewswire/ -- Texas Instruments Incorporated (TI) today introduced the industry's smallest low-power digital temperature sensor with SMBus/two-wire serial interface. Packaged in a SOT563, which is only 0.6mm tall including the leads, the TMP102 is 30 percent smaller than other leaded devices available today. The sensor features low quiescent current of 10uA (maximum) in the active mode and 1uA (maximum) in the shutdown mode. The extremely small size and the low power requirement make the TMP102 suitable for portable consumer electronics and other battery-powered end equipment. (See http://www.ti.com/tmp102-pr.)

The TMP102 is well-suited for applications where space is at a premium such as laptop thermal protection, mobile phones and portable fitness equipment. The sensor is powered from a supply range of 1.4V to 3.6V, so the TMP102 can take advantage of an existing 1.8V power bus and be added to any system with a minimum of external passives. The TMP102 has an address pin that can be used in combination with SDA and SCL to generate four different addresses therefore allowing up to four TMP102 sensors to be on the same SMBus. The sensor also includes a SMB alert function.

The TMP102 is typically accurate to 0.5C over the temperature range from -25C to +85C. The 12-bit resolution of the sensor provides a measurement precision of 0.0625C.

Available Today

The TMP102 is available now from TI and its authorized distributors in a tiny SOT563 package. It is priced at $0.80 each in 1000-piece quantities (suggested resale pricing).

TI offers analog engineers a wide-ranging support infrastructure that includes training and seminars, design tools and utilities, technical documentation, evaluation modules, an online KnowledgeBase, a product information hotline and a comprehensive offering of samples that ship within 24 hours of request.
