Magnetic Speed Sensors

The Infineon XENSIV™ TLE4929C-XHA products address new requirements for crankshaft speed sensing from hybrid powertrains. An advanced vibration detection algorithm ensures valid sensor data for any hybrid powertrain traction mode e.g. detecting unintended movements of the crankshaft while the car is driven by the e-motor. This improves efficiency of the engine start and helps to avoid misfiring or error messages by ECU caused by wrongly calibrated sensor data.XENSIV™ TLE4929C-XHA sensors as well feature high adaptivity to the diversity of crankshaft application. Using the adaptive K-Factor the default 50% switching threshold (Bmax – Bmin) can be trimmed to 16 values between 40 and 60% which allows to optimize phase accuracy for different encoder designs. Compared to predecessor products from Infineon also encoders with 34 or 56 teeth are supported now.The PG-SSO-3-53 package with Ni plating, 3-wire voltage I/F and increased supply/output capacitance of up to 470nF/1,8nF supports high EMC robustness and with its unchanged mechanical specification a high backward compatibility with predecessor products TLE4929C-XVA, TLE4929C-XAF and TLE4929C-XAN is given and design switch cost are minimized.

The Infineon XENSIV™ TLE4988C products feature advanced camshaft sensing performance and improved application adaption. One major benefit of the advanced sensor performance is the reduced dependence from rare-earth backbias magnets for module manufacturers. The TLE4988C has proven right performance with a ferrite backbias magnet for all relevant parameters such as phase jitter, phase accuracy or speed effect across key temperature, air gap and rpm ranges.With automatic in-car calibration a most accurate sensing in real application environment is ensured addressing tolerances of ferromagnetic wheels and magnetic encoders, as well as mounting tolerances of the sensor. The TLE4988C products furthermore allow to compensate for thermal or mechanical stress applied in the module manufacturing process. The embedded EEPROM can also feature a unique chip ID to allow logistic traceability (on request). A new high speed digital I/F allows a fast read out of registers for diagnosis or test purposes.Infineon´s TLE4988C products are available optimized for the use with three different backbias magnet materials, such as Fe (link to), SmCo and NdFe (link to). All products come inside the well established Camshaftsensor package PG-SSO-3-52 with Sn plating, 3-wire voltage I/F and increased supply/output capacitance of 220/1,8nF for higher EMC robustness. With unchanged mechanical specification of the package a high backward compatibility with predecessor products from Infineon is given and design switch cost are minimized.

The Infineon XENSIVTM TLE4922 is an active mono cell Hall sensor ideally suited for detecting the motion and position of ferromagnetic and permanent magnet structures. An additional self-calibration module has been implemented to achieve optimum accuracy during normal running operation. There are two different types of our TLE4922 available, the TLE4922-XAN and the TLE4922-XIN version. Both types have passed qualification at Tj=155°C. The difference of both devices consists in their field of usage and the duration of the qualification run.TLE4922-XAN type has passed 2000 hour qualification run and is suited for speed measurements in 2-wheeler application with asupply voltage of 9VTLE4922-XIN has passed 5000 hour qualification run being suitable for 12V automotive applications

Infineons´ XENSIV TLE4959-5U magnetic sensor comes in a RoHs compliant four-pin package, qualified for automotive usage. The recommended capacitors increase the EMC robustness of the device. In 12 V applications it is further recommended to use a serial resistor RSupply for protection on the supply line. A pull-up resistor RLoad is mandatory on the output pin and determines the maximum current flowing through the output transistor. Avalue of 1.2 kΩ is recommended for the 5V application

Infineon´s differential Hall effect sensor TLE4921-5U provides a high sensitivity and a superior stability over temperature and symmetrical thresholds in order to achieve a stable duty cycle. TLE4921-5U is particularly suitable for rotational speed detection and timing applications of ferromagnetic toothed wheels such as anti-lock braking systems, transmissions, crankshafts, etc. The integrated circuit (based on Hall effect) provides a digital signal output with frequency proportional to the speed of rotation. Unlike other rotational sensors differential Hall ICs are not influenced by radial vibration within the effective air-gap of the sensor and require no external signal processing.
