MEMSIC Inc. announced a new family of acceleration and tip-over sensor components that includes four new sensors, the MXD6240 and 41AU, MXC6244AU, MXC6245XU.
These new sensors provide tip-over and acceleration sensing in a wide range of automotive, industrial, and consumer applications, such as motorcycle and off-road vehicle tip-over detection, vehicle navigation, and Digital SLR camera horizontal position detection.
- 624x family uses MEMSIC’s proprietary thermal accelerometer technology that uses heated gas molecules to sense acceleration instead of a mechanical beam structure, the transducer exhibits a natural low-pass frequency response with virtually no mechanical resonance and extremely high accuracy over a range of temperatures
- MXD6240 and MXD6241AU are autonomous inclination sensors with eight built-in, pin-programmable tip-over angle thresholds from 40 to 70 degrees, making them ideal for tip-over applications where no microcontroller is available. If the device orientation with respect to vertical exceeds the programmed threshold angle, the digital output changes state to alert the system to a tip-over or fall-down event. In addition to the transducer’s inherent low-pass response, an internal anti-vibration filter provides >45dB attenuation above 25Hz, and >60dB attenuation above 50Hz
- MXC6244AU and MXC6245XU are complete 2 axis I2C interface accelerometers each with 1 mg of resolution. The MXC6244AU is ±8g full-scale range device. It includes the internal anti-vibration filter and the eight angle thresholds programmable through the I2C interface
- MXC6245XU is a ±2g full-scale range device and is targeted at cost sensitive applications not requiring the programmable anti-vibration filter or the eight programmable tip-over angle thresholds offering 12 bits of resolution (1 mg) and has the same outstanding over-temperature bias performance of typically 0.1 mg/C
