AS5200L
12-Bit On-Axis Magnetic Rotary
Position Sensor with Redundant I²C
and PWM Outputs
General Description
The AS5200L is an easy to program stacked dual die magnetic
rotary position sensor with redundant high-resolution 12-bit
I²C or PWM outputs. 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.
AS5200L 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.

General Description
Applications
The AS5200L is ideally suited for embedded automotive
applications where the sensor output is read by a close MCU.
The two separate sensor dies enable for safety-critical
automotive applications like gear-shifters, contactless knobs,
pedals, joysticks and other angular position measurement
solutions.
