AH4930Q
AUTOMOTIVE 3D MAGNETIC LINEAR
HALL SENSOR WITH I2C INTERFACE Description Pin Assignments The AH4930Q automotive 3D magnetic chip is a miniature monolithic
sensor IC sensitive to the three orthogonal components of the flux
density applied to the IC. On-chip integrated temperature sensor data
is available for system functions such as junction temperature
indication and temperature compensation of magnetic field
measurement. A precision analog signal-path along with integrated
ADC digitizes the measured analog magnetic field values, and this
allows the AH4930Q with the correct magnetic circuit to decode the
absolute position of any moving magnet. With its magnetic field
detection in x, y, and z-direction the sensor reliably measures threedimensional, linear and rotation movements. (Top View) SCL/INT The AH4930Q measurement data can be read over I2C bus. The
sensor is runtime programmable and offers on-chip temperature
compensation of the measured units. The selectable power mode
control unit enables micro-power and continuous measurement
functionality. Applications include joysticks, control elements (white
goods, multifunction knops), or electric meters (anti-tampering) and
any other application that requires accurate angular measurements or
low power consumptions. GND 2 GND 3 Applications •
