FAQ

What is the magnetic operating point (BOP) and release point (BRP) for TLE4983CHTNE6847HAMA1?

The typical magnetic operating point (BOP) is ±15 mT and release point (BRP) is ±12 mT, measured at 25 °C with defined ramp rate and target geometry. These values are temperature-compensated across the full operating range, ensuring consistent switching behavior from –40 °C to +150 °C junction temperature.

Does TLE4983CHTNE6847HAMA1 require an external pull-up resistor?

Yes - its differential open-drain outputs (OUTA/OUTB) require external pull-up resistors on the ECU side, typically 4.7 kΩ to 5 V or 12 V. The internal output stage does not include pull-ups, enabling flexible voltage-level interfacing with various ECU input architectures.

Can this sensor be used with non-ferrous targets such as aluminum or copper?

No - the TLE4983CHTNE6847HAMA1 is optimized for ferromagnetic targets (e.g., steel gears). Non-ferrous materials do not concentrate magnetic flux sufficiently to trigger reliable switching; use only with steel, iron, or appropriately magnetized composite targets.

Is TLE4983CHTNE6847HAMA1 qualified to AEC-Q100 Grade 0?

Yes - it is qualified to AEC-Q100 Grade 0 (–40 °C to +150 °C), with full characterization including HTOL, TC, UHAST, and ESD testing. This qualification covers both die and final packaged device, supporting use in critical engine bay locations.
