Overview
The MMA8491Q Xtrinsic 3-axis accelerometer is an ultra-low-power tamper detection and tilt sensor
that enables smart meters, home appliances, asset tracking applications, gaming and remote controls
through auto-on/auto-sleep energy-efficient operation housed in a specialized industrial package.
The MMA8491Q Xtrinsic accelerometer is simple, yet robust with reduced system and implementation
cost for reduced development time. Its unique single sample and hold measurement method allows
for ease of use.

The MMA8491Q Xtrinsic accelerometer is simple, yet robust with reduced system and implementation
cost for reduced development time. Its unique single sample and hold measurement method allows
for ease of use.
The MMA8491Q Xtrinsic accelerometer operates with reduced power consumption by intelligently
determining when the application should operate at a low-power mode or shut off, therefore
prolonging battery life. The tilt threshold detection is used to enable/disable host systems or trigger
actions, which reduces duty cycles and saves power. Set up is not required since the auto-on
provides a short wait to the first data out, reducing average power consumption to less than one
micro amp. Without software load on the core system, more sleep time is possible on the host,
which also saves power.
