HallLinear PWM with Caps Description

The linear Hall IC TLE4998P3C has been designed specifically to meet the requirements of highly accurate rotation and position detection, as well as for current measurement applications. Two capacitors are integrated on the lead frame, making this sensor especially suitable for demanding EMC requirements .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). 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.The IC is produced in BiCMOS technology with high voltage capability, also providing reverse polarity protection. Digital signal processing, using a 16-bit DSP architecture together with digital temperature compensation, guarantees excellent long-time stability as compared to analog compensation methods. While the overall resolution is 16 bits, some internal stages work with resolutions up to 20 bits. The PWM output frequency can be selected within the range of 122 Hz up to 1953 Hz.
