Infineon TLE4998C3CHAMA1

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.

Symbol Views

(not all views will be available for every part)

Normal: Standard and most popular representation of schematic symbol

ALT_1 (IEEE view): Symbol representation in a way that is more graphical in explaining what the purpose of each pin is. For connectors and most discretes (as we use these views) it is simply an alternate view for people to use depending on the situation. For instance connectors can be generally an input, an output or neither. Resistors can be vertical or horizontal.

ALT_2 (demorgan): Demorgan is a name for an equivalent Gate structure. so for instance an AND gate and an OR gate can be represented by its Demorgan equivalent of a NOR gate.

Sometimes a device is fractured into multiple symbols (often for high pin count parts). If that is the case, you can preview the different symbols that make up the device by selecting them in this drop down.
