Electrical and Magnetic Characteristics

Product characteristics involve the spread of values guaranteed within the specified voltage and ambient

temperature range. Typical characteristics are the median of the production.

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

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.
