The AS5601-SO_EK_ST is an evaluation board for magnetic sensors, specifically a multifunctional magnetic angle/speed sensor IC making use of Hall technology. It is designed to enable experimentation in various application fields and working principles.

This evaluation board provides a high degree of flexibility and scalability to allow designers to evaluate different Hall sensor configurations with different sensor elements and sensitivity. These magnetic sensors are used for a variety of purposes, ranging from rotary speed measurement in turbines and engines to reading the position of a permanent magnet in a robotic arm.

Hall sensors typically consist of three components: a magnetic flux concentrator, a Hall element, and an external magnet. The magnetic flux concentrator focuses the field of any externally placed magnet towards the Hall element, which generates an output voltage proportional to the strength of the field. The magnetic flux concentrator helps to reduce signal errors due to external disturbances and unwanted magnetic fields.

The AS5601-SO_EK_ST board features an integrated Hall element and a winder for the magnetic flux concentrator. It also includes an analog/digital converter, temperature sensor, digital filters, and a temperature compensation circuit. This enables the user to evaluate the performance of the Hall element in different conditions and applications.

The board operates on the principle of detecting the magnitude and direction of the magnetic flux being generated by the external magnet. The flux is transferred through the winder to the Hall element, which outputs a signal that is proportional to the flux. This signal is then converted to an analog output voltage, which can then be read by the analog-to-digital converter. The data is then processed by the digital filters and the temperature compensation circuit in order to accurately measure the angle of rotation and speed.

The AS5601-SO_EK_ST board is ideal for applications such as industrial motor control, robotics, positioning systems, and automotive engine speed measurement. It has a wide operating range from -45°C to +135°C and can operate in magnetic fields up to 5 gauss. The evaluation board is available in both 3.3 V and 5 V versions, making it suitable for numerous applications.

The AS5601-SO_EK_ST board offers an intuitive user interface for evaluation, making it easy for users to set up the board and adjust parameters. All the necessary software and drivers are provided, and the board can be connected to a computer via USB for easy data acquisition and control. This evaluation board serves as an ideal platform for designers to test and experiment with various magnetic sensors and magnetic sensing principles.
