Target applications
The TLE4966L is an integrated circuit double 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 IC provides a speed signal at Q2 for every magnetic
pole pair and a direction information at Q1, which is provided before the speed signal.

The chopped Double Hall Switch comprises two Hall probes, bias generator, compensation circuits, oscillator,
and output transistors.
The bias generator provides currents for the Hall probes 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
probes caused by molding and soldering processes and other thermal stresses in the package. This chopper
technique together with the threshold generator and the comparator ensures high accurate magnetic switching
points.

over operating range, unless otherwise specified. Typical values correspond to VS = 12 V and TA = 25°C
To operate the sensor at the max. switching frequency, the magnetic signal amplitude must be 1.4 times
higher than for static fields. This is due to the -3 dB corner frequency of the low pass filter in the signal
path.
Systematic delay between magnetic threshold reached and output switching
Jitter is the unpredictable deviation of the output switching delay
BREP is equivalent to the noise constant
Time from applying VS ≥ 2.7 V to the sensor until the output state is valid
Thermal resistance from junction to ambient
Calculation of the ambient temperature:
e.g. for VS = 12.0 V, IStyp = 5.5 mA, VQSATtyp = 0.3 V and 2 x IQ = 10 mA :
Power Dissipation: PDIS = 72.0 mW.
In TA = Tj – (RthJA × PDIS) = 175°C – (190 K/W × 0.072 W)
Resulting max. ambient temperature: TA = 161.3°C
