Texas Instruments TMP103 Digital Temperature Sensor

Texas Instruments introduced the TMP103 digital temperature sensor. The TI TMP103 features a two-wire interface that is compatible with both I2C and SMBus interfaces. Up to eight TMP103′s can be tied together in parallel and easily read by the host. The TMP103 sensor consumes 97% less power and is 75% smaller than the next closest competitor. The TMP103 is available now in a 0.76-mm x 0.76-mm four-ball wafer chip-scale package (WCSP). It is priced at $0.39 in 1,000-unit quantities.

TI TMP103 Features

  • Maximum of 1 uA while in shutdown mode and 3 uA while in active mode to extend battery life
  • In active state, draws about half the power of the next closest competitor in shutdown state
  • Measures only 0.76 mm x 0.76 mm
  • Global read/write functionality reduces software development and processor loading
  • With a single command, the software can poll up to eight devices, reducing MIPS and bandwidth on the I2C bus
  • Capable of reading temperatures to a resolution of 1°C
  • Two-wire interface that is compatible with both I2C and SMBus interfaces
  • Interface supports multiple device access (MDA) commands that allow the master to communicate with multiple devices on the bus simultaneously
  • Ideal for space-constrained, power-sensitive applications with multiple temperature measurement zones that must be monitored
  • Consumes 97% less power and is 75% smaller than the next closest competitor
  • Simplifies thermal profiling while enabling longer battery life and smaller form factors for portable consumer electronics such as smartphones, tablets, laptops and netbooks
