AS5200L-AMFM

AS5200L 12-Bit On-Axis Magnetic Rotary Position Sensor with Redundant IC and PWM Outputs The AS5200L is an easy to program stacked dual die magnetic General Description rotary position sensor with redundant high-resolution 12-bit IC 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 IC 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. Ordering Information and Content Guide appear at end of datasheet.
