TLE4988C Technical Product Description Programmable True Power On Camshaft Sensor About this Document High-level description of the product features and technical characteristics as primary information about the functionality of the TLE4988C High End Camshaft Speed Sensor. Product Description The TLE4988C is an active Hall sensor ideally suited for camshaft applications and similar industrial applications, such as speedometer. It provides true power on (TPO) functionality from zero speed and maps the mechanical shape of a target wheel, such as either a tooth or a notch into a unique electrical output state. Variants of self-calibration algorithms are implemented, adaptable to common camshaft targets in order to achieve optimum phase accuracy in operation. TPO capability and cancelation of production spread and assembly tolerance can be achieved by end of line programming. Features Mono-cell chopped Hall switching sensor to measure speed or phase of tooth/pole wheels Digital output signal (voltage interface) with enhanced micro break feature True Power On functionality (TPO) with optional automatic TPO adaption in EEPROM Configurable algorithms in EEPROM, incl. Individual Switching Threshold with vibration suppression End-of-line programmable switching points (k-factor), options for hidden, visible and adaptive switching hysteresis, programmable delay time Temperature coefficient of back-bias magnet pre-programmed High immunity against ESD, EMC and mechanical stress 3-pin package PG-SSO-3-52.

It has two integrated capacitors on the lead frame (220 nF/1.8 nF). These capacitors increase the EMC robustness of the device. In 12 V applications it is further recommended to use a serial resistor R (dependent on EMC Supply requirement 47 to 100 ) for protection on the supply line. A pull-up resistor R determines the maximum Load current flowing through the output transistor, 1.2 k is recommended.
