1 / 5 page [AK09970] Product brief 2017/1 - 1 - 1. Genaral Description AK09970 is a 3-axis magnetic sensor IC with high sensitivity and wide measurement range utilizing our latest hall sensor technology. Our ultra-small package of AK09970 incorporates magnetic sensors, chopper stabilized signal, amplifier chain, and all necessary interface logic for detecting weak to strong magnetic fields in the X, Y and Z planes independently. From its compact foot print, thin package, and extremely low power consumption, it is suitable for a wide range of applications such as connected home, door & window opening/close sensing, and magnetic tamper detection of IoT systems or smart meters just to name a few. 2. Features Functions: 16 bit data out for each 3-axis magnetic component Programmable threshold 3-axis magnetometer Built-in A to D Converter for magnetometer data output Selectable sensor measurement range and sensitivity setting High sensitivity setting Sensitivity: 1.1 µT/LSB (typ.) Measurement range: ± 36 mT Wide range setting Sensitivity: 3.1 µT/LSB (typ.) Measurement range: X and Y-axis ±34.9mT, Z-axis ±101.5mT Serial interface I2C bus interface Standard and Fast mode compliant with Philips I2C specification Ver.2.1 4-wire SPI Operation mode Power-down, Single measurement, Continuous measurement 3-axis programmable switch function Output pin for event notification INT pin and OD-INT pin DRDY function for measurement data ready Magnetic sensor overflow monitor function Built-in oscillator for internal clock source Selectable sensor drive Low power drive / Low noise drive Operating temperatures: -4 0˚C to +85˚C Operating supply voltage: +1.7V to +3.6V Current consumption (VDD = +1.8V): Power-down: 2.0 nA (typ.)
