TLE4928C E6547

Überblick

XENSIV(TM) high-performance speed sensor with high accuracy and sensitivity

Infineon´s proven family of TLE492x differential Hall speed sensors is designed for a broad range of high-performance speed sensing applications, even in harsh environments.

The sensor combines a fast power up time with high accuracy and sensitivity. Providing a wide temperature range, high ESD robustness and large EMC resistance the TLE4928(C) perfectly meets the requirements of harsh environmental conditions, prevalent in automotive applications. The TLE4928(C) comes with the well established PG-SSO package - with and without two integrated capacitors. With all these features TLE4928(C) is the ideal fitting Hall based crankshaft and transmission speed sensing solution for today’s automotive requirements.
