The linear Hall IC TLE4998C3C has been designed specifically to meet the requirements
of highly accurate angle and position detection as well as for current measurement
applications. Two capacitors are integrated on the lead frame, making this sensor
especially suitable for applications with demanding EMC requirements.
The sensor provides a digital SPC (Short PWM Code) signal, based on the standardized
SENT (Single Edge Nibble Transmission, SAE J2716) protocol. The SPC protocol
allows transmissions initiated by the ECU. Two further operation modes are available:
• “range selection” for dynamical switching of the measurement range during operation
• “ID selection” to build a bus system with up to 4 ICs on a single output line and a
Each transmission sequence contains an adjustable number of nibbles representing the
magnetic field, the temperature value and a status information of the sensor. The
