TLE4922XINFHALA1

TLE4922-XIN-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 (2- and 3 wheeler) applications. Crankshaft speed and position sensing Figure 1-2 Package PG-SSO-4-1 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 protection at the output Over temperature shutdown at the output and Reverse voltage protection Figure 1-3 Pinning, Sensitive Area 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 V DD Wide operating temperature range - T : -40 C - 155 C junction Hall Analog Digital Supply Supply Supply True zero speed up to 8kHz signal frequency GND Enabling Low Power Application: Idd = 5mA at Vdd = 9V Large operating voltage range of 4.5V up to 18V D-Core Chopped Open Tracking (Min/Max, Robustness against wheel run outs enables to sense broad range Hall V Q ADC Drain Offset, Probe Comparator ) of wheels Figure 1-4 Blockdiagram TLE4922 V BA TT V LOAD RSERIES R LOAD 200 1.2 k V DD VBA TT C VDD Q I Q 47 nF GND IC V 1 Q C Q CLOAD TLE4922 4.7 nF 50 pF Figure 1-1 Application circuit TLE4922 Figure 1-5 Wheel with sensor Product Type Marking Ordering Code Package TLE4922-XIN-F 22BAA2 SP001154230 PG-SSO-4-1 Data Sheet 1 V 1.0, 2016-11-21TLE4922-XIN-F Specification 2 Specification The listed characteristics are ensured over the operating range and lifetime of the integrated circuit. 2.1 Absolute Maximum Ratings Table 2-1 Absolute Maximum Ratings Parameter Symbol Values Unit Note or Test Condition Min.

Note: Stresses above the max. values listed here may cause permanent damage to the device. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Maximum ratings are absolute ratings exceeding only one of these values may cause irreversible damage to the integrated circuit. 2.2 Operating Range The following operating conditions must not be exceeded in order to ensure correct operation of the IC. All parameters specified in the following sections refer to these operating conditions unless otherwise mentioned. Table 2-2 Operating Range Parameter Symbol Values Unit Note or Test Condition Min.

As soon as back bias magnet is attached or customer mold covers the TLE4922 this value will decrease due to larger surface JA and mass of the module. Maximum exposure time at other junction temperatures shall be calculated based on the values specified using the Arrhenius-model. 2) Maximum one additional pulse may occur due to temperature variation during stand still.
