Product Overview
The TLE4953C E0184 and TLE4953 E0184 are differential two-wire Hall Effect sensor ICs designed for detecting rotation direction. These single-chip solutions offer improved airgap performance, dynamic self-calibration, and adaptive hysteresis, making them suitable for applications requiring detection from 0 speed up to 4.5kHz. They are designed for coarse transmission target wheels and are highly resistant to piezo effects, operating across a wide temperature range.

| Magnetic Characteristics | ||||
| Limit threshold speed | BLimit | 0.35 (min), 0.8 (typ), 1.84 (max) | mT | Max. is 5 value at Tj<145C 1) Magnetic amplitude values, sine magnetic field, limits refer to the 0% criteria just 1pulse is missing out of 100. Only valid at lowest PGA stage/highest amplification because of adaptive hysteresis. |
| Limit differential direction signal | BDir | 0.08 (min), 0.54 (typ) | mT | Calculated at two consecutive threshold crossing 2) Magnetic peak to peak value, not subject to production test - verified by design/characterization. No part of the FAR procedure. Max is 5 value of characterization of distribution at Tj<145C, with 0% criteria, just one pulse is missing out of 100. |

Note on Vibration Suppression: The performance of the vibration suppression algorithm is dependent on the typical value of the differential direction signal limit. The TLE4953/C E0184 has a reduced value for extended airgap performance, which consequently reduces its vibration suppression capabilities.
