The AS5043 is a magnetic rotary position sensor based on contactless pole determination technology. This technology utilizes a small magnet attached to the rotor shaft to enable pole-based angular position detection without physical contact. The AS5043 is an integrated magnetic angular position sensor and provides a digital angle output over an SPI or PWM interface.The AS5043 combines a sin/cos analog-to-digital converter, a digital processor, and an OTP memory to provide a complete solution for angular position detection. Its high resolution and excellent linearity make it ideal for use in motion control applications such as automotive and robotics. The device is also suitable for applications that require reliable and precise angular measurements, such as security sensors and medical imaging.The AS5043 is a low-cost, low-power, single-channel magnetic rotary position sensor. It features a high dynamic range of operation and a low noise level. The sensor provides angle accuracy down to 0.1°. This accuracy helps make the device suitable for use in applications that require precise angular measurements such as motor control and detection systems, imaging systems, navigational systems, and health monitoring systems.The AS5043 is packaged in a 3mm × 3mm, 12-pin W-DFN package and is supplied in two temperature grades: Industrial (-40°C to+125°C) and Automotive (-40°C to+105°C).The AS5043’s working principle is based on an OTP memory that stores user-specific information. This includes the ID (device ID), the position (angle), and other specific parameters which are written during the device programming phase. A series of logic blocks and algorithms are used to process the signal from the magnet attached to the motor’s rotor shaft. The AS5043 is able to detect and resolve the magnetic poles’ transition patterns with a high degree of accuracy.The device communicates over both a SPI and PWM interface. The SPI interface offers a faster transmission rate, while the PWM interface can be used in applications that require low power consumption. The application field for the AS5043 is quite broad, as it can be used in a variety of different sectors. For automotive and robotics, the device is ideal for use in motion control applications due to its high resolution and excellent linearity. The device is also suitable for security sensors and medical imaging, as its accuracy helps make it reliable for those applications.The AS5043 is an integrated magnetic rotary position sensor that provides high-resolution angle detection and is easy to use. Its low-cost, low-power, and high-performance capabilities make it suitable for use in a variety of applications in a wide range of sectors. It has a high dynamic range of operation, low noise level, and can detect and resolve magnetic pole transitions with an accuracy of 0.1°. Moreover, the AS5043 is available in two temperature grades to fit different needs and can be programmed to meet specific user requirements. The device’s changeable interfaces (SPI and PWM) also offer flexibility.
