描述 Description

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.
