LIS2DH

LIS2DH MEMS digital output motion sensor: ultra low-power high performance 3-axis “femto” accelerometer Features ■ Wide supply voltage, 1.71 V to 3.6 V ■ Independent IOs supply (1.8 V) and supply voltage compatible ■ Ultra low-power mode consumption down to 2 µA ■ ±2g/±4g/±8g/±16g dynamically selectable full- scale ■ I2C/SPI digital output interface ■ 2 independent programmable interrupt generators for free-fall and motion detection ■ 6D/4D orientation detection ■ “Sleep to wake” and “return to sleep” function ■ Freefall detection ■ Motion detection ■ Embedded temperature sensor ■ Embedded FIFO ■ ECOPACK® RoHS and “Green” compliant Applications ■ Motion activated functions ■ Display orientation ■ Shake control ■ Pedometer ■ Gaming and virtual reality input devices ■ Impact recognition and logging LGA-14 (2.0x2.0x1 mm) Description The LIS2DH is an ultra low-power high performance three-axis linear accelerometer belonging to the “femto” family, with digital I2C/SPI serial interface standard output. The LIS2DH has dynamically user selectable full scales of ±2g/±4g/±8g/±16g and it is capable of measuring accelerations with output data rates from 1 Hz to 5.3 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 interrupt signals by two independent inertial wake-up/free-fall events as well as by the position of the device itself. The LIS2DH is available in small thin plastic land gri...
