AS5145B-EK-AB-STM1.0: 360º Magnetic Position Sens

Summary

The AS5145B Eval-Kit is designed to adapt standard size stepper motors with a contactless rotary position sensor. Rotation of the magnet holders is sensed by the rotary position sensor, soldered on the PCB board.

The AS5145 is a contact less magnetic rotary encoder for accurate angular measurement over a full turn of 360 degrees.

It is a system-on-chip, combining integrated Hall elements, analog front end and digital signal processing in a single device.

To measure the angle, only a simple two-pole magnet, rotating over the center of the chip, is required. The magnet can be placed above or below the IC.

The absolute angle measurement provides instant indication of the magnet’s angular position with a resolution of 0.0879º = 4096 positions per revolution. This digital data is available as a serial bit stream and as a PWM signal.

An internal voltage regulator allows the AS5145 to operate at either 3.3V or 5V supplies.
