Infineon Technologies AG Magnetic speed sensors TLE4943C

Description
TLE4943C - Hall based differential wheel speed sensor with AK Protocol Infineon´s XENSIVTM TLE4943C is an integrated, active magnetic field sensor for wheel speed applications based on Hall technology. Its basic function is to measure the speed of a pole wheel or a ferromagnetic toothed wheel. It has a two wire-current interface using the AK protocol for communication. This protocol provides beside the speed signal additional information as direction of wheel rotation and air gap information. The sensor combines a fast power-up time with a low cut-off frequency. Excellent sensitivity and accuracy combined with its wide operational temperature range makes the sensor ideally suited for harsh automotive requirements. The TLE4943C is additionally provided with an overmolded 1.8nF capacitor for improved EMC performance. Summary of Features • Two wire current interface according AK protocol • Hall based principle • Integrated magnetic field sensor for wheel speed measurement • Detection of rotation direction • Additional air-gap information • Single chip solution • High sensitivity • Large operating air-gaps • Magnetic pre-induction possible • Automotive qualified temperature ranges from TJ= -40°C to 150°C • 1.8nF overmolded capacitor • Wide operating range from 6.5V to 20V • Green package with lead-free plating Potential Applications Wheel speed sensing in harsh automotive environments Applications Chassis, safety and ADAS
