The TLE4955HALA1 is a magnetic sensor designed for linear and compass applications. The sensor is built with Hall-effect technology and provides robust magnetic performance over a wide variety of conditions. It can detect magnetic fields up to ±45mT and operate within an extended temperature range of -40°C to 125°C. The TLE4955HALA1 is ideal for applications such as linear and compass position measurement, machine control and navigation.

The principle of the TLE4955HALA1 is based on the Hall effect. The Hall effect is a physical phenomenon in which a voltage is induced across a conductor in a magnetic field. In the TLE4955HALA1, a thin film Hall plate is integrated. Along with the integrated amplifier, the Hall plate converts the magnetic field into an analog voltage output, proportional to the magnetic field strength. This output voltage can then be processed for a variety of applications.

The TLE4955HALA1 is designed to be used in linear and compass applications. The linear application is used for accurate linear position measurements, linear speed measurements, or full linear range measurements using a scalable sinusoidal signal. For the compass application, the sensor can detect the direction of the earth’s magnetic field to provide precise direction information for navigation, object tracking, and navigation control.

The TLE4955HALA1 is provided in a 3.0 mm x 3.5 mm TDFN package, making it suitable for size-constrained applications. The sensor features a single-supply voltage of 3.3 V, a quiescent current of 3 μA, and an offset voltage of ±50 mV. The dynamic range of the sensor is between 4mT and 37mT, with a detection resolution of 0.09mT. The sensor also features a temperature range of -40°C to 125°C.

In addition to the features mentioned above, the TLE4955HALA1 offers a wide range of features for its linear and compass applications: High-resolution direction measurement with 1° of accuracy; suppression of AC and DC offsets; compensation of magnetoresistance and self noise contributions; leakage currents; linearity error of 0.01%; balanced signal; improved temperature stability; and integrated fault protection.

The TLE4955HALA1 provides robust magnetic performance in a wide variety of conditions and requires a minimum number of external components, making it an ideal solution for linear and compass applications. This sensor is suitable for use in a variety of applications such as linear and compass position measurement, machine control and navigation.
