Target Applications
Target applications for TLE4906-2K are all automotive applications which require a high precision Hall switch for
position sensing with a operating temperature range from -40°C to +150°C. The TLE4906-2K is a unipolar Hall
switch which is actuated with the south pole of a magnet. A magnetic field above the threshold BOP switches the
output to low (output transistor ON) and a magnetic field below the release point BRP back to high (transistor OFF).

Functional Block Description
The chopped Hall IC Switch comprises a Hall probe, bias generator, compensation circuits, oscillator and output
transistor.
The bias generator provides currents for the Hall probe and the active circuits. Compensation circuits stabilize the
temperature behavior and reduce technology variations.
The Active Error Compensation rejects offsets in signal stages and the influence of mechanical stress to the Hall
probe caused by molding and soldering processes and other thermal stresses in the package.
This chopper technique together with the threshold generator and the comparator ensure high accurate magnetic
switching points.

Application circuit
It is recommended to use a series resistor RS with 200Ω and a capacitor of CDD = 4.7nF for protection against
overvoltage and transients on the supply line. A capacitor CQ at the Q pin protects the IC from disturbances
coupled to the output. A pull-up resistor RQ is also required for the output pin Q.

1) over operating range, unless otherwise specified. Typical values correspond to VDD = 12V and TA = 25°C
2) To operate the sensor at the max. switching frequency, the value of the magnetic signal amplitude must be 1.4 times higher
than for static fields. This is due to the -3dB corner frequency of the low pass filter in the signal path.
3) Systematic delay between magnetic threshold reached and output switching.
4) Jitter is the unpredictable deviation of the output switching delay.
5) Time from applying VDD ≥ 2.7V to the sensor until the output state is valid.
6) Thermal resistance from junction to ambient.
Calculation of the ambient temperature:
e.g. for VDD = 12.0V, IDDtyp = 4mA, VQSATtyp = 0.3V and IQ = 20mA
Power dissipation PDIS = 54.0mW
In TA = Tj - (RthJA x PDIS) = 175°C - (100K/W x 0.054W)
Resulting max. ambient temperature: TA = 169.6°C
