Accelerometer Slices Power, Packs Embedded Algorithms

Logging in as an efficient power saver, the KXTE9 digital-output, tri-axis accelerometer employs embedded algorithms for orientation and activity monitoring to simplify motion-based functionality in consumer electronics. Setting the operating-power consumption bar to what the maker says is the market’s lowest, typical operating current for a fully operational KXTE9 is 30 µA. According to the company, this takes down the historical, industry-expected current consumption of 200 to 300 µA. In addition to orientation detection, the component features an activity-monitoring function that reports changes in motion state, either active or inactive. The KXTE9 operates from a 1.8V to 3.6V supply, is RoHS compliant, halogen-free, and comes in a 3 mm x 3 mm x 0.9 mm LGA package. KIONIX INC., Ithaca, NY. (607) 257-1080.
