Infineon Simplifies Speed ​​Sensor Design with TLE4922 Sensor and Speed ​​Sensor 2Go Kit

Sensor development kits from Infineon will significantly reduce design effort, thereby reducing development time and system costs. In order to achieve fast and reliable speed measurement, Infineon Technologies AG has introduced a new Hall sensor TLE4922 and its companion "Speed ​​Sensor 2Go" design kit. The TLE4922 was developed specifically for industrial and automotive applications where fast and reliable speed measurement is critical, such as speed detection of crankshafts and gearboxes in two-wheelers and tricycles. Industrial applications include production and building automation and speed monitoring of electric drive control devices.

TLE4922 ensures reliable speed measurement and reduces system costs

The TLE4922 Hall sensor reliably measures magnetic field changes. This means that it can be used for speed detection of many types of wheels, such as magnetic encoder wheels or ferromagnetic gears. In addition to a wide range of applications, the TLE4922 also helps reduce system costs. For example, it supports the use of simple and cost-effective back magnetism while achieving high air gap performance and phase accuracy. The sensor is also very robust against vibration and air gap jumps, enabling accurate speed detection in a very wide magnetic field range of +/- 400 mT. The larger operating range simplifies the circuit design and improves the sensor's flexibility and robustness. This makes the installation of the sensor easier, thus further helping to reduce system costs.

TLE4922 is especially suitable for TIM (Twist independent installation) configuration. Therefore, it can replace the passive speed sensor in the motor and in the two-wheeled vehicle and automobile wheels. Compared to passive speed sensors, the TLE4922 can accurately measure speeds starting at 0 Hz. In addition, it also has good jitter performance and provides many protection features to prevent short circuit, overheating and reverse voltage. Good electromagnetic compatibility (EMC) and ESD robustness make it suitable for use in harsh environments. Its operating voltage is 4.5 V to 18 V and its operating temperature range is -40°C to 155°C. The sensor is available in a 4-pin SSO package.
