HALL VALUE TEMP. CRC Product Brief TLE4998x Programmable Linear Hall Sensor family with 12bit and 16bit digital output TLE4998x family VDD Interface Bias Supply Spinning HALL EEPROM A OUT D DSP Temp. Sense A OUT Generation D GND ROM Features With the introduction of the TLE4998x product family, Infineon offers an extensive product portfolio of Linear Hall sensors for automotive and industrial systems. The TLE4998x is based on a similar concept as the TLE4997. The analog interface implemented in the TLE4997 is replaced by a selection of digital output protocols. The interface options of the TLE4998x include Pulse Width Modulation (PWM), Single Edge Nibble Transmission (SENT) as well as Short PWM Codes (SPC). The sensor is conveniently programmable in EEPROM and is available in three different leaded packages. With its temperature and stress compensation features, it provides outstanding performance stability over both temperature and lifetime.
