Circuit 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.

1) over operating range, unless otherwise specified. Typical values correspond to VS =12 V 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 - 3 dB 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 VS ≥ 2.7 V to the sensor until the output state is valid
6) Thermal resistance from junction to ambient
Calculation of the ambient temperature (SC59 example)
e.g. for VS = 12.0 V, IStyp = 4 mA, VQSATtyp = 0.3 V and IQ = 20 mA :
Power Dissipation: PDIS = 54.0 mW.
In TA = Tj – (RthJA × PDIS) = 175°C – (100 K / W × 0.054 W )
Resulting max. ambient temperature: TA = 169.6°C
