TLE4922-XAN-F

TLE4922-XAN-F 1 Product Description The TLE4922 is an active mono cell Hall sensor suited to detect 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. 1.1 Target Application The TLE4922 is a speed sensor especially optimized for small engine (2and 3 wheeler) applications. Crankshaft speed and position sensing Transmission speed on output shaft Speedometer application Excellent sensitivity and accuracy combined with its wide operational temperature range makes the sensor ideally suited for harsh environments. 1.2 Key Features and Benefits Twist independent mounting (TIM) “enables one sensor fits all” Small thin package (PG-SSO-4-1) Protected against harsh environment due to – Short-circuit current limitation at the output – Over temperature shutdown at the output and – Reverse voltage protection Supreme performance due to adaptive symmetrical hysteresis / threshold Independent of back bias magnet polarity due to ±400mT full scale range Enhanced EMC & ESD robustness - ESD : ±3kV HBM Wide operating temperature range - Tjunction: -40 °C - 155 °C True zero speed up to 8kHz signal frequency Enabling Low Power Application: Idd = 5mA at Vdd = 9V Large operating voltage range of 4.5V up to 18V Robustness against wheel run outs enables to sense broad range of wheels Figure 1-2 Package PG-SSO-4-1 Figure 1-3 Pinning, Sen...
