Product Description
Product Description
The TLE4922 is an active mono cell Hall sensor designed for detecting motion and position of ferromagnetic and permanent magnet structures. It features a self-calibration module for enhanced accuracy during operation. This sensor is optimized as a speed sensor for small engine applications (2- and 3-wheelers), including crankshaft speed and position sensing, transmission speed on the output shaft, and speedometer applications. Its excellent sensitivity, accuracy, and wide operational temperature range make it suitable for harsh environments.
Key Features and Benefits:
- Twist independent mounting (TIM) for universal fit.
- Small, thin PG-SSO-4-1 package.
- Protected against harsh environments with short-circuit current limitation, over-temperature shutdown, and reverse voltage protection.
- Supreme performance through adaptive symmetrical hysteresis/threshold.
- Independent of back-bias magnet polarity with a 400mT full-scale range.
- Enhanced EMC & ESD robustness (ESD: 3kV HBM).
- Wide operating temperature range (Tjunction: -40 C to 155 C).
- True zero speed up to 8kHz signal frequency.
- Enables low-power applications (Idd = 5mA at Vdd = 9V).
- Large operating voltage range (4.5V to 18V).
- Robustness against wheel run-outs for sensing a broad range of wheels.
Target Applications:
- Crankshaft speed and position sensing
- Transmission speed on output shaft
- Speedometer application
