Infineon TLE49662KHTSA1

The TLE4966-2K is an integrated circuit dual Hall-effect sensor designed specifically for highly accurate applications. Precise magnetic switching points and high temperature stability are achieved by active compensation circuits and chopper techniques on chip. The sensor provides two independent speed outputs at Q1 and Q2 with the status (high or low) corresponding to the magnetic field value at the respective Hall element H1 and H2 . Both Hall elements have the identical thresholds for B OP and B RP (B OP1 = B OP2 and B RP1 = B RP2). For positive magnetic fields (south pole) exceeding the threshold B OP1 and/or B OP2 the corresponding output Q1 and/or Q2 is low, whereas for negative magnetic fields (north pole) lower than B RP the output switches to high. Due to the spatial distance of the two Hall elements on the chip (d = 1.45mm) the two output signals will show a phase difference in case the sensor is used with a rotating magnetized pole wheel.

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.
