1 Typical values are at TA = 25°C and VCC = 12 V. Performance may vary for individual units, within the specified maximum and mini-
mum limits.
2 Maximum voltage must be adjusted for power dissipation and junction temperature; see Power Derating section.
3 VCC represents the generated voltage between the VCC pin and the GND pin.
4 The value of dI is the difference between 90% of ICC(H) and 10% of ICC(L), and the value of dt is time period between those two
points. The value of dI/dt depends on the value of the bypass capacitor, if one is used, with greater capacitances resulting in lower
rates of change.
5 For t > tPO(max), and BRP < B < BOP, POS is undefined.
6 Maximum current limit is equal to the maximum ICCL(max) + 3 mA.
7 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 rela-
tive 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).
