• Manufacturer Part Number: tle5010
• Description: Gmr Based Angular Sensor
• Manufacturer: Infineon Technologies Corporation

Draft
2.4
The GMR sensor is implemented in vertical integration. This means, that the GMR active
areas are integrated above the logic part. GMR elements change their resistance
depending on the direction of the magnetic field.
4 individual GMR elements are connected to one Wheatstone sensor bridge.
They sense either the
• X component, V
• Y component, V
of the applied magnetic field.
The advantage of a full-bridge structure is that the GMR signal amplitude is doubled.
