AK09970, 3-Axis Magnetic Sensor with Digital Outpu

Asahi Kasei Microdevices Corporation’s (AKM) AK09970 is a 3-axis magnetic sensor integrated circuit utilizing AKM’s latest Hall sensor technology which offers high sensitivity and a wide measurement range. The sensor is able to detect magnetic signals in X, Y, and Z directions and can output the result as a digital data supporting I2C and SPI communication. The product offers a wide measurement range and high resolution in an ultra-small package of a 16-WFQFN package that includes the chopper stabilized signal, amplifier chain, and all necessary interface logic for detecting magnetic fields.

Features
  • Magnetic field output (digital)/data ready alert (DRDY bit)
    • Measures magnetic field on all 3-axis via intermittent drive and outputs the result as digital data
  • Magnetic event interrupt function
    • Magnetic event interrupt pins allow for two thresholds that can be programmed for each axis
    • Magnetic fields that exceeds the threshold, it outputs a "magnetic event" interrupt to registers
  • High sensitivity setting/wide range setting
    • High sensitivity setting of ±36 mT on 3-axis
    • Ability to measure a wide range of magnetic fields from µT to mT
    • Wide range setting of 101 mT can be achieved via the Z-axis
  • Low power consumption when battery life is critical
    • Operate at only a few µA
Security Applications
  • IoT applications
  • Open and close detections
  • Monitoring factory equipment
