Smart & Contactless Potentiometer www.ams.com/AS5600 AS5600 – 12-bit On-Axis Magnetic Rotary Position Sensor with analog or PWM output - Ideal for contactless potentiometers - Highest reliability and durability - Simplest angular excursion programming - Automatic low power mode We provide innovative analog solutions to the most challenging applications in sensor and sensor interfaces, power management, and wireless. General Description The AS5600 is an easy to program magnetic rotary position sensor with a high-resolution 12-bit analog or PWM output. This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. This AS5600 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. The default range of the output is 0 to 360 degrees. However, full resolution of the AS5600 can be applied to smaller range by programming a zero angle (start position) and a maximum angle (stop position). The AS5600 is also equipped with a smart low power mode feature to automatically reduce the power consumption. The device is available in a small form factor, compact 8-pin SOIC package. Benefits Features - Highest reliability and durability - Simple programming - Great flexibility on angular excursion - High-resolution output signal - Selectable output - Low-power consumption - Contactless angle measurement - Simple user-programmable start and stop positions over the I²C interface - Maximum angle programmable from 18° upt to 360° - 12-bit DAC output resolution - Analog output ratiometric to VDD or PWM-encoded digital output - Automatic entry into low-power mode - Automatic magnet detection -Easy start and stop position programming in 3 wire mode without programmer Applications - Contactless potentiometers - Contactless knobs -Pedals - RC servos - Angular position measurement solutions AS5600 Block Diagram VDD3V3 SDA SCL DIR Register Setting VDD5V I²C LDO 3.3V PGO OTP Hall Sensors Analog Front-End AFE PWM 12-bit A/D ATAN (CORDIC) Digital Processing and Filtering Driver OUT 12-bit D/A AGC AS5600 Magnetic Core GND www.ams.com [email protected] © 06/2014 by ams Subject to change without notice Headquarters ams AG Tobelbader Strasse 30, 8141 Unterpremstaetten, Austria Phone +43 3136 500-0 · Fax +43 3136 525-01 Sales Offices Worldwide [email protected] [email protected] [email protected]
