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
