Product Specification
| Description | SSO-2 Switches (Solid State) RoHS | Mfr. Part # | TLE4941-1C |
| Package | SSO-2 | Model Number | TLE4941-1C |
The TLE4941-1 and TLE4941-1C are differential two-wire Hall Effect sensor ICs designed for wheel speed applications. These sensors track the magnetic input signal, monitoring it within a digital circuit. They are suitable for applications requiring reliable speed detection, with features that adapt to signal amplitude and initial offset during startup. The devices transition from an uncalibrated mode, where offset is determined by peak detection, to a calibrated mode where the output switches at zero-crossing of the input signal.
