TMR3022 Datasheet | MultiDimension

Version 1.2.2 High Performance Automotive TMR Angle Sensor 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 singleended voltage. The Wheatstone bridge structure of the TMR effectively pensates 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...
