The linear Hall IC TLE4998S has been designed specifically to meet the requirements
of highly accurate rotation and position detection, as well as for current measurement
applications.
The sensor provides a digital SENT signal based on the SAE J2716 standard, which
consists of a sequence of pulses. Each transmission has a constant number of 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.
The IC is produced in BiCMOS technology with high voltage capability, and it also has
reverse-polarity protection.
