Go for Infineon quality
Analog TMR sensors for highly accurate position detection. Discover our leading solutions for TMR-based sensors.
Tunneling Magneto Resistive (TMR) technology is offering high sensing sensitivity with a high output voltage so that no internal amplifier – thus the magnetic sensor can be connected directly to the microcontroller without any further amplification. In addition, TMR technology shows a very low temperature drift reducing external calibration and compensation efforts. The TMR technology is also well known for its low current consumption.
With the XENSIVTM TLE5501 products, Infineon launched the first angle sensor products based on TMR technology. TMR magnetic sensor TLE5501 is available in two versions TLE5501 E0001(automotive qualified) and TLE5501 E0002 (automotive ASIL).
The TLE5501 is a 360° TMR-based angle sensor that detects the orientation of a magnetic field. This is achieved by measuring sine and cosine angle components with Tunneling Magneto Resistance (TMR) elements. These raw signals (sine and cosine) are provided as a differential output signal and can directly be further processed within a microcontroller. The large output voltage of the bridge renders any further signal amplification unnecessary.
