TI's digital temperature sensor cuts power consumption, size more than 75 percent
Texas Instruments unveiled the industry’s smallest, most power-efficient digital temperature sensor. The TMP103 consumes 97 percent less power and is 75 percent smaller than the next closest competitor. 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 TMP103 simplifies thermal profiling while enabling longer battery life
and smaller form factors for portable consumer electronics such as smartphones,
tablets, laptops and netbooks.

Key features and benefits:
- 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, the TMP103 draws
approximately half the power of the next closest competitor in shutdown
state.
- Measures only 0.76 mm x 0.76 mm, making it suitable for high-density,
space-constrained applications requiring multiple temperature measurement
zones.
- 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.
- Complements TI's extensive portfolio of analog and embedded processing
products for the portable consumer electronics market, including battery
management, interface, audio codecs and wireless connectivity.
Tools and support
An evaluation module is available now
for the TMP103 for $49. An IBIS model to verify board signal integrity
requirements is also available.
Package, availability and pricing
The TMP103 is
available now in a 0.76-mm x 0.76-mm WCSP package for a suggested retail price
of $0.39 in 1,000-unit quantities.
