magnetic fi elds. This so-called algebraic convention supports arithmetic comparison of north and south polarity values, where the
relative strength of the fi eld is indicated by the absolute value of B, and the sign indicates the polarity of the fi eld (for example, a
–100 G fi eld and a 100 G fi eld have equivalent strength, but opposite polarity).
Magnetic fl ux density, B, is indicated as a negative value for north-polarity magnetic fi elds, and as a positive value for south-polarity
When operating at maximum voltage, never exceed maximum junction temperature, T
Device will survive the current level specifi ed, but operation within magnetic specifi cation cannot be guaranteed.
Short circuit of the output to VCC is protected for the time duration specifi ed.
Maximum specifi cation limit is equivalent to I
