Infineon TLE4998C4 Programmable Linear Hall Sensor for Precision Current Sensing Applications

The increasing demand for energy efficiency and precise control in automotive, industrial, and consumer applications has driven the need for highly accurate and reliable current sensing solutions. The Infineon TLE4998C4 stands out as a programmable linear Hall sensor specifically engineered to meet these stringent requirements, offering exceptional performance in precision current sensing applications.

This sensor integrates a Hall plate, analog signal conditioning, and a digital interface into a single device. Its programmability is a key feature, allowing engineers to precisely calibrate parameters such as sensitivity, offset, and temperature compensation through a serial interface (SENT or PWM output). This flexibility ensures optimal performance across diverse operating conditions, making it highly adaptable to various system designs. The TLE4998C4 provides high accuracy and stability over a wide temperature range (-40°C to 150°C), which is critical for applications exposed to harsh environments, such as automotive systems.

A major advantage of the TLE4998C4 is its ability to enable non-intrusive current measurement. By placing the sensor near a current-carrying conductor, it accurately measures the magnetic field generated by the current, eliminating the need for shunt resistors and reducing power losses. This makes it ideal for use in electric power steering, battery management systems, and overcurrent protection circuits, where efficiency and reliability are paramount.

Furthermore, the device supports multiple output formats, including SENT (Single Edge Nibble Transmission), which is widely adopted in automotive applications for its robustness and noise immunity. Its programmability also allows for customized response characteristics, enabling designers to tailor the sensor’s behavior to specific application needs without hardware modifications.

In summary, the Infineon TLE4998C4 combines programmability, high precision, and robust performance, making it a superior choice for advanced current sensing solutions.
