Acceleration sensors are designed to detect changes in force resulting from tilt, motion, positioning, shock and vibration. For consumer electronics that require a fast response time, high sensitivity, low-current consumption, low-voltage operation and a standby mode in a small profile package, Freescale’s acceleration sensors are an ideal solution.
One of the primary applications of Freescale’s acceleration sensors is in the use of next-generation automotive airbag systems. Freescale’s inertial acceleration sensors are engineered to detect an automobile crash by measuring the abrupt deceleration of a vehicle and then triggering air bag deployment. The accelerometers’ advanced transducer design enhances sensor offset performance and over-damping response, which helps improve system reliability and resistance to high-frequency and high-amplitude parasitic vibrations. The devices are designed to help distinguish airbag system conditions that might trigger a false deployment, such as a door slam or high vibrations during vehicle assembly.
Freescale has created three types of inertial acceleration sensors to detect these changes: Low g, Medium g and High g acceleration sensors.
