Medium-g accelerometers

STMicroelectronics has introduced a three-axis sensor with digital output that can detect accelerations up to 24g. The sensor’s combination of multiple full-scale ranges above 10g with small size, high resolution, low power consumption and embedded features enable high-precision motion sensing in a range of consumer and industrial applications. The new MEMS accelerometer provides accurate output across full-scale ranges of ±6/±12/±24g. The medium-g sensing enables high-level vibration monitoring and high-shock detection without any loss of information. In game applications, medium-g detection enhances user interfaces. Two separate, highly programmable interrupt signals enable immediate notification of desired events, such as when the acceleration value goes above/below a user-defined threshold. The company’s motion sensor can be programmed to work in the sleep-to-wake-up mode. In this mode, the accelerometer keeps the read chain active, consuming less than 10uA, and wakes up when an event occurs, automatically increasing the output data rate. The accelerometer boasts high stability over a wide temperature range for both zero-g offset and sensitivity. Its compact design provides high shock survivability up to 10,000g.
