3-axis accelerometer for non-safety automotive applications

The AIS3624DQ is an ultra-low-power high-performance three-axis linear accelerometer with a digital serial interface SPI standard output. An I2C compatible interface is also available.

The device features ultra-low-power operational modes that allow advanced power saving and smart sleep-to-wakeup functions.

The AIS3624DQ has dynamically user-selectable full scales of ±6g/±12g/±24g and is capable of measuring accelerations with output data rates from 0.5 Hz to 1 kHz.

The self-test capability allows the user to check the functioning of the sensor in the final application.

The device may be configured to generate an interrupt signal by inertial wakeup/free-fall events as well as by the position of the device itself. Thresholds and timing of interrupt generators are programmable by the end user on the fly.

The AIS3624DQ is available in a small quad flat no-lead (QFN) package (4x4 mm footprint) and is guaranteed to operate over an extended temperature range from -40 °C to +105 °C.

This product may be used in a variety of automotive non-safety applications such as motion-activated functions, telematic boxes, impact recognition and logging, and vibration monitoring and compensation.
