Linear Hall IC

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 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 common supply, which can be individually accessed by the ECU. Each transmission sequence contains an adjustable number of nibbles representing the magnetic field, the temperature value and a 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. Digital signal processing using a 16-bit DSP architecture together with digital temperature compensation guarantee excellent long-time stability compared to analog compensation methods. While the overall resolution is 16 bits, some internal stages work with resolutions up to 20 bits.

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.The IC is produced in BiCMOS technology with high voltage capability, also providing reverse polarity protection.
