Product Overview
The MEMSIC MXC6244AU is a highly accurate 2-axis accelerometer system featuring a programmable internal anti-vibration filter. This device excels in high vibration environments, offering significant attenuation of unwanted signals and preventing false readings. It includes an internal angle detection circuit with programmable thresholds for tip-over or fall-down event alerts, offloading processor burden. The MXC6244AU utilizes MEMSIC's proprietary thermal accelerometer technology, ensuring robustness, reliability, and high accuracy over temperature with exceptional shock tolerance and no possibility of stiction or mechanical resonance. It operates from a single 2.7V to 5.5V supply and is available in a compact 6-pin LCC package.
