S8960B is a high-precision MEMS dynamic accelerometer designed for automotive HMIs (human/machine interfaces) applications. In automotive HMIs, it generates input feedback from the driver or passenger when the vehicle is moving or when pressing buttons in the cockpit.

This device combines a MEMS accelerometer with advanced digital processing technologies to accurately detect and measure acceleration and angular movement in all three axes. The onboard data processing automatically adjusts the sensitivity according to the actual application needs. The S8960B is capable of measuring acceleration up to 2.2G and angular rate up to 1000°/s.

The S8960B can be used in a wide range of applications, including airbag deployment systems, headlamp level control, windscreen wiper system controls, in-vehicle infotainment applications, as well as in navigation systems. It is ideal for use in advanced driver assistance systems (ADAS) because of its high accuracy, fast response time, and small size. Additionally, the S8960B is designed with an integrated EEPROM for storing calibration parameters.

The working principle of the S8960B is based on principles of electrostatic sensing and electrostatic motion detection. In a simplified overview, the device measures the acceleration or angular rate along the three axes by detecting the electrostatic forces or torques generated by the accelerometer\'s MEMS moving mass elements interacting with the electrodes. The output signal from the MEMS structure is then digitized and calibrated by an on-board processor, which makes the device completely programmable for a wide variety of applications.

The S8960B is an ideal choice for automotive applications, because it features a combination of high accuracy, low power consumption, and accelerated response time. It has the capability to sense the force, torque, displacement, or angular rate on all three axes. Its programmable parameters enable it to be tuned to the needs of the specific application. Additionally, its small size and low power consumption make it an optimal solution for automotive HMIs.
