Kionix announced the expansion of its digital-output, tri-axis accelerometer product line with the KXTE9 product series. With embedded algorithms for orientation and activity monitoring, the KXTE9 simplifies the adoption of increasingly-popular, motion-based functionality in consumer electronics while reducing operating power consumption to very low levels for such feature-rich products.
The advanced, orientation-detection feature of the KXTE9 reports changes in landscape, portrait, face-up, and face-down conditions. This sophisticated, embedded algorithm eliminates the need for continuous data collection and complex calculations by a microprocessor. Accordingly, the KXTE9 enables the implementation of screen rotation—such as that found on some high-end mobile phones— into any handheld device. With a few adjustable parameters, the screen-rotation algorithm can be optimized for an intuitive user experience.
In addition to orientation detection, the KXTE9 features an activity-monitoring function. This function reports changes in a device’s motion state, either moving (active) or not moving (inactive). By providing this information to the device, the KXTE9 enables power management, a critical function in today’s mobile devices for prolonging battery life, and other novel motion-based applications.
A highly-manufacturable product with consistent product performance across use conditions, the KXTE9 operates across a supply voltage of 1.8V to 3.6V DC. The part is RoHS compliant, halogen-free, and delivered in a 3x3x0.9mm LGA package.
