Electrical and Magnetic Parameters

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:

DIS = 54.0 mW.

A = Tj – (RthJA × PDIS) = 175°C – (100 K / W × 0.054 W )

Resulting max. ambient temperature:

TA = 169.6°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.
