KMX61G Mag-Accel Combo Industry’s First Micro-Amp Magnetic Gyro FEATURES APPLICATIONS 6-axis mag-accel with emulated gyro output Small footprint (3x3x0.9mm) Magnetometer auto-calibration and magnetic interference rejection algorithms Embedded temperature sensor User-configurable motion wake-up and backto-sleep functions Programmable interrupt engine 512-byte FIFO buffer with watermarking capability User Interface Power Management Active/Inactive Monitoring Device Orientation Inclination and Tilt Sensing Gesture Recognition Activity Monitoring FOR Smartphones and Mobile Devices Laptops Gaming and Virtual Reality Health and Fitness PRODUCT OVERVIEW The KMX61G is a high-performance, low-power, accelerometer-magnetometer device enhanced with integrated sensor fusion software and auto-calibration algorithms to deliver the industry’s first highly accurate gyro emulation. Optimized for mobile applications, the KMX61G requires only 450μA of power – significantly less than any consumer gyro available today. The KMX61G also offers a wide range of embedded functionality, including user-configurable motion wake-up and back-to-sleep functions, a programmable interrupt engine, and accelerometer self-test function.
