描述 Description

The linear Hall IC TLE4998S8D has been designed specifically to meet the requirements of highly accurate angle and position detection. The sensor provides a digital SENT signal based on the SAE J2716 standard, which consists of a sequence of pulses. Each transmission consists of multiple data nibbles containing the Hall value, the temperature and status information of the sensor. The output stage is an open-drain driver pulling the output pin to low only. Therefore, the high level needs to be obtained by an external pull-up resistor. This output type has the advantage that the receiver may use an even lower supply voltage (e.g. 3.3 V). In this case the pull-up resistor must be connected to the given receiver supply.
