... TLE4925 TLE4925C General Information The TLE4925/TLE4925C is an active Hall sensor suited to detect the motion and position of ferromagnetic and permanent magnet structures. An additional self- calibration module has been implemented to achieve optimum accuracy during normal running operation. It comes in a three-pin package for the supply voltage and an open drain output ...

... Figure 2: Block Diagram of TLE4925/TLE4925C Circuit Description The TLE4925/TLE4925C is comprised of a supply voltage regulator, a pair of hall probes, spaced at 2.5mm, differential amplifier, noise-shaping filter, comparator, advanced digital signal processor (DSP), A/D and D/A converter and an open drain output. Startup mode: The differential signal is digitized in the A/D converter and fed into the dsp part of the circuit ...
Page 4
Running mode: In running mode the output is triggered by the comparator. An offset cancellation feedback loop is formed by the A/D converter, dsp and offset cancellation D/A converter. In running mode switching always occurs at zero-crossing only ...

... Two possible applications are shown in Figure 6 and Figure 7 (Toothed and Magnet Wheel). The difference between two-wire and three-wire application is shown in Figure 10 for the TLE4925C and in Figure 11 for the TLE4925. Gear Tooth Sensing In the case of ferromagnetic toothed wheel application the IC has to be biased by the south or north pole of a permanent magnet (e.g. SmCO VX145)) with the dimensions 8 mm × ...
