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

via PRNewswire

DALLAS , Sept. 21 /PRNewswire/ -- Texas Instruments Incorporated(NYSE: TXN) (TI) today introduced the industry's smallest low-power digitaltemperature 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 smallerthan other leaded devices available today. The sensor features low quiescentcurrent of 10uA (maximum) in the active mode and 1uA (maximum) in the shutdownmode. The extremely small size and the low power requirement make the TMP102suitable for portable consumer electronics and other battery-powered endequipment. (See

The TMP102 is well-suited for applications where space is at a premiumsuch as laptop thermal protection, mobile phones and portable fitnessequipment. The sensor is powered from a supply range of 1.4V to 3.6V, so theTMP102 can take advantage of an existing 1.8V power bus and be added to anysystem with a minimum of external passives. The TMP102 has an address pin thatcan be used in combination with SDA and SCL to generate four differentaddresses therefore allowing up to four TMP102 sensors to be on the sameSMBus. 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 measurementprecision of 0.0625C.

Available Today

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