Infineon Technologies TLE5501 E0001 & E0002 XENSIV™ Magnetic Sensors
Infineon Technologies TLE5501 E0001 & E0002 XENSIV™ Magnetic Position Sensors are analog TMR-based angle sensors for any kind of angular position sensing. 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.
The TLE5501 E0001 is qualified according to AEC-Q100 and is pin-compatible to Infineon's established and market-proven TLE5009. No additional amplifier is necessary, enabling the creation of lower-cost systems.
The TLE5501 E0002 meets ISO 26262 Standards and is a milestone with regard to functional safety. This makes Infineon reach the automotive functional safety grade ASIL D for angle sensors - with only one single sensor chip. TLE5501 E0002 incorporates decoupled bridges for redundant external angle calculation and also offers high diagnostic coverage.
Since this TMR-based sensor doesn't require an additional internal amplifier, it can be connected directly to a microcontroller without further amplification. TMR also shows a very low-temperature drift reducing external calibration and compensation efforts. In addition, TMR technology is also well known for its low current consumption.
