MXC6244AU
- Overview
- Specifications
- Features and Benefits
- Applications
The MXC6244AU is a complete 2 axis accelerometer system with a programmable internal anti-vibration filter. This filter can provide as much as 45dB attenuation above 25Hz, and 60dB attenuation above 50Hz. In addition, the device has 8 built in, I2C programmable angle thresholds. If the device orientation with respect to vertical exceeds the programmed threshold angle, the INT output changes state to alert the system to a tip-over or fall down event. This feature can offload the processor from the burden of continuously calculating angles. In the case of an INT, the processor can begin calculating angles to allow for user-defined algorithms to be implemented
