The linear Hall IC TLE4998P 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 PWM signal, which is ideally suited for direct decoding by
any unit measuring a duty cycle of a rectangular signal (usually a timer/capture unit in a
microcontroller). Furthermore, it is possible to attach an external lowpass filter, which
allows an A/D conversion using the sensor supply voltage as a reference.
The output stage is an open-drain driver pulling the output pad to low only. Therefore,
the high level must be obtained by an external pull-up resistor. This output type has the
advantage that the receiver may use even a lower supply voltage (e.g. 3.3 V). In this
case, the pull-up resistor must be connected to the given receiver supply.
