The KMA36 digital position sensor IC combines a magnetoresistive element along with analog to digital converter and signal processing in a standard small TSSOP package. By using Anisotropic Magneto Resistive (AMR) technology, the KMA36 is able to determine accurately and contactless the magnetic angle of an external magnet over 360°, as well as the incremental position on a magnetic pole strip with 5 mm pole length. Its sleep and low power mode as well as automatic wakeup over I2C make the KMA36 ideal for many battery applications. Position data can be transmitted using a PWM or digital two-wire (SDA, SCL) communication bus. Using the programmable parameters of this digital position sensor, the user can have access to a wide range of configuration parameters to ensure the maximum of freedom and functionalities.
