The TLE 4924C 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 4924C 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 4924C sup-

ports 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 4924C perfectly meet the requirements of harsh environmental con-

ditions prevalent in automotive applications. The TLE 4924C comes with the

well established PG-SSO package with two integrated capacitors and various

hysteresis concepts. With all the features, the TLE 4924C is the ideal fitting hall

based crankshaft speed sensing solution for today‘s automotive requirements.

TLE 4924C is perfectly suited for applications with:
