1 When operating at maximum voltage, never exceed maximum junction temperature, TJ(max). Refer to power derating curve charts.
2 Device will survive the current level specified, but operation within magnetic specification cannot be guaranteed.
3 Short circuit of the output to VCC is protected for the time duration specified.
4 Maximum specification limit is equivalent to ICC(max) + 3 mA.
5 Magnetic flux density, B, is indicated as a negative value for north-polarity magnetic fields, and as a positive value for south-polarity
magnetic fields. This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the
relative strength of the field is indicated by the absolute value of B, and the sign indicates the polarity of the field (for example, a
–100 G field and a 100 G field have equivalent strength, but opposite polarity).
