July 12, 2017, Infineon's sensor development kit will greatly reduce the design workload, thereby reducing development time and reduce system costs. In order to achieve fast and reliable speed measurement, Infineon Technologies AG (launched the new Hall sensor TLE4922 and supporting the 'Speed ​​Sensor 2Go' design kit.TLE4922 for industrial and automotive applications and development, in these applications, fast and reliable speed Sensor It is important, for example, to detect the speed of crankshafts and gearboxes in two-wheeled and tricycles, and industrial applications include speed testing of production and building automation and electric drive control devices.

  The TLE4922 Hall sensor reliably measures magnetic field changes. This means that it can be used for multi-class wheel speed detection, such as magnetic encoder wheels or ferromagnetic gears. In addition to a wide range of applications, TLE4922 also helps to reduce system costs. For example, it supports the use of simple and cost-effective back magnetic, while achieving high air gap performance fuel metering valve and phase accuracy. The sensor is also very strong in resistance to vibration and air gap jumps, enabling accurate speed detection within +/- 400 mT wide magnetic field. Larger working range simplifies circuit design and improves sensor flexibility and robustness. This makes the sensor easier to install, thus further helping to reduce system costs.

T LE4922 is particularly suitable for TIM configuration. Therefore, it can replace the motor and the two wheels and the car wheel on the passive speed sensor. Compared to the passive speed sensor, TLE4922 can accurately measure the starting speed to 0 Hz. In addition, it also has good jitter performance, and provides a number of protection features to prevent short circuit, overheating Throttle Position Sensor and reverse voltage. Good electromagnetic compatibility (and ESD robustness makes it suitable for use in harsh environments with operating voltages from 4.5 V to 18 V and operating over the -40 ° C to 155 ° C temperature range. The sensor is available in a 4-lead SSO package The

  With the 'Speed ​​Sensor 2Go' kit, developers can easily and quickly evaluate TLE4922. You can very quickly understand the work of TLE4922 in a variety of applications. The initial measurement can be done in just a few minutes. The Speed ​​Sensor 2Go kit includes sensor modules, interface boards, and cables. The sensor module integrates the TLE4922 sensor and ferrite magnets. The interface board has two XMC microcontrollers: one for triggering and one for debugging. The USB cable provided in the kit is available for PC connection. Graphical user interface (GUI) -based evaluation tools can record Pressure Switch and graphically display velocity data. In addition to the 'Speed ​​Sensor 2Go' kit, Infineon offers additional support for sensor simulation, software-based development tools such as System C models or special assessment tools.
