AS5600L-ASOM

Product Document Published by ams OSRAM Group AS5600L 12-Bit Programmable On-Axis Magnetic Rotary Position Sensor General Description The AS5600L is an easy to program 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 AS5600L 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 AS5600L is also equipped with a smart low power mode feature to automatically reduce the power consumption. An input pin (DIR) selects the polarity of the output with regard to rotation direction. If DIR is connected to ground, the output value increases with clockwise rotation. If DIR is connected to VDD, the output value increases with counterclockwise rotation. The AS5600L is available in a standard SOIC-8 package and in a WL-CSP for applications requiring small-sized sensing solutions with a size of 2.07mm x 2.63mm x 0.6mm. Both variants are qualified for a temperature range from -40°C to 125°C. Ordering Information and Content Guide appear at end of datasheet.
