[ ak 099 70 ] product brief 2017 / 1 - 2 - 3. overview the ak09970 supports wide measurement range with high resolution in 3 - axis detection and captures magnetic fields in 3 - dimensions. with these abilities, it is great device for controlling the direction of security cameras and connected home, (smart home, smart house), smart locks, along with door and window open/close detection. ak09970 has the following main features : (1) wide measurement range & high resolution the ak09970 has a wide measurement range of 35mt on 3 axes. in addition, further range of 101mt can be achieved via the z axis. it is able to measure a wide range of magnetic field from microtesla to millitesla such as from geomagnetic to a magnet since it has high measurement resolution of 1.1ut/lsb in high resolution mode. (2) low - power consumption when battery life is critical the ak09970 can operate using only a few a, thus consuming a very low current that satisfies a demand of iot products, (refer to the specification table). it contributes to a long battery life of a product that needs constant acquisition of sensor data to monitor an object?s status. (3) magnetic field output (digital)/ data ready alert (drdy bit) the ak09970 measures magnetic field on all 3 - axes via intermittent drive and outputs the result as digital data, (suppo rting i2c/spi communications). it outputs a da ta ready alert to the dedicated register when the measurement data is updated. (0.25/0.5/1/1 0/20/15/100hz interval modes or singl e measurement mode for intermittent drive options.) (4) magnetic event interrupt function the ak09970 has magnetic event interrupt pins. two thresh olds can be programmed for each axis, (setting the resolution equal to the measuring resolution). when a magnet ic field that exceeds the threshold is sent, the ak09970 outputs a ?magnetic event? interrupt to registers or external output pins. the magnetic event that causes an interrupt output that can be selected freely by setting a register. (data ready alert men tioned in 3 can also be output from an interrupt pin). two interrupt pins are available for magnetic event: the int pin for push - pull output and the odin pin for open- drain output. therefore, the output format can be selected depending on the customer?s product.
