Application Field

SX5148P3KWT1 accelerometer is a versatile device with a wide range of applications. It is widely used in automotive safety systems, in order to detect and respond to sudden accelerations or decelerations of the vehicle, which could lead to crashes. The device is also used in vehicle stability control systems, providing information on the acceleration or deceleration of the vehicle, as well as its direction and speed. Additionally, the device is used in crash sensors, providing data related to the crash severity and impact direction.

Working Principle

SX5148P3KWT1 accelerometer works by measuring acceleration or motion using a sensitive seismic mass, low-noise coreless audio interface, and an advanced signal conditioning ASIC. The seismic mass is composed of a low mass element suspended along two axis by flexures. When the device is subject to acceleration, the mass is displaced, triggering a change in capacitance that is used to calculate acceleration. The coreless audio interface is used to further process the analog signal and output a digital signal, which can then be used by the device.
