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.

1) over operating range, unless otherwise specified. Typical values correspond to VDD = 12V 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 -3dB 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 VDD ≥ 2.7V to the sensor until the output state is valid.
6) Thermal resistance from junction to ambient.
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
