Description

The TMR3022 angle sensor is designed with two sets of redundant Wheatstone bridge structures, each consisting of four high-sensitivity tunneling magnetoresistance (TMR) sensor elements, forming two sets of half-bridge structures that separately output SIN single-ended voltage and COS single-ended voltage. The Wheatstone bridge structure of the TMR effectively compensates for the sensor’s temperature drift.

A magnet is placed above the TMR3022 to provide a working magnetic field parallel to the surface of the chip. When the magnet rotates, the chip outputs a voltage signal that is a sine and cosine related to the angle of the magnetic field.

The redundant design of the TMR3022 improves the robustness of the application system. The TMR3022 achieves very low angle error when the magnetic field is maintained within the range of within 200 Gs to 800 Gs. The sensor is available in the TSSOP8 package.
