The TLE 4927C detects the motion and position of ferromagnetic and permanent magnet structures by measuring the differential flux density of the magnetic field. A self-calibration mode ensures optimum accuracy. Few transitions after start up the sensor has already finished self-calibration and has reached a high-accuracy running mode. As the TLE 4927C is switching at visible fixed (-1) or visible adaptive (-2) hysteresis, the sensor enables accurate operation even at large pitches known from e.g. VR applications. Therefore the TLE 4927C supports cost effective transitions from passive to active sensing. The sensor combines a fast power up time with high accuracy and sensitivity. With a wide temperature range, high ESD robustness and large EMC resistance, the TLE 4927C perfectly meet the requirements of harsh environmental conditions prevalent in automotive applications. The TLE 4927C comes with the well established PG-SSO package with two integrated capacitors and various hysteresis concepts. With all the features, the TLE 4927C is the ideal fitting hall based crankshaft speed sensing solution for today‘s automotive requirements.
