(ppr), 256 edges per revolution, 1.4 per step Two diagnostic outputs are provided to indicate an out-of- - Index output (one pulse per revolution) range condition of the magnetic field as well as movement - Accurate user programmable zero position (0.35) of the magnet in Z-axis. In addition a specific combination of output states indicate a loss of power supply. - Failure detection mode for magnet placement monitoring and loss of power supply The AS5035 is available in a small 16pin SSOP package. It - Wide temperature range: - 40C to + 125C can be operated at either 3.3V or 5V supplies. - Small lead-free package: SSOP 16 (5.3mm x 6.2mm) 3 Applications Industrial applications: - Robotics - Replacement of optical encoders - Flow meters - Man-machine interface Automotive applications: - Power seat position sensing Figure 1: Typical arrangement of AS5035 and magnet - Power mirror position sensing 1.1 Benefits 4 Pin Configuration - Complete system-on-chip, including analog front end and digital signal processing - 2-channel quadrature and index outputs provide an alternative to optical encoders - User programmable Zero positioning by OTP allows easy assembly of magnet - Diagnostic features for operation safety - Ideal for applications in harsh environments due to magnetic sensing principle - Robust system, tolerant to magnet misalignment, air gap variations, temperature variations and external magnetic stray fields Figure 2: AS5035 Pin configuration SSOP16 - No calibration required Revision 1.5 www.austriamicrosystems.com Page 1 of 17 ams AG Technical content still valid
