General Description

The AS5200L is an easy to program stacked dual die magnetic rotary position sensor with a high-resolution 12-bit I2C or PWM output. This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. This AS5200L is designed for contactless potentiometer applications and its robust design eliminates the influence of any homogenous external stray magnetic fields.
The industry-standard I2C interface supports simple user programming of non-volatile parameters without requiring a dedicated programmer. By default the output represents a range from 0 to 360 degrees. It is also possible to define a smaller range to the output by programming a zero angle (start position) and a maximum angle (stop position). The AS5200L is also equipped with a smart low power mode feature to automatically reduce the power consumption. This device is designed for automotive applications and is AEC-Q100 grade 1 qualified. To enable safety-critical applications it has two separate sensor dies in one MLF-16 (5x5) package with wettable flanks.

With two decades of magnetic sensor system know-how, we have broad experience in selecting the most suitable magnets. ams experts recommend the following magnet suppliers.

This product suits for the following applications:

  • Gear-shifters
  • Contactless knobs
  • Pedals
  • Joysticks
  • Angular position measurement solutions
