Typical values are at T
A
= 25°C and V
CC
= 12 V. Performance may vary for individual units, within the specified maximum and minimum
limits.

Maximum voltage must be adjusted for power dissipation and junction temperature; see
Power Derating
section.

V
CC
represents the generated voltage between the V
CC
pin and the GND pin.
4
The value of dI is the difference between 90% of I
CC(H)
and 10% of I
CC(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.

Maximum current limit is equal to the maximum I
CCL(max)
+ 3 mA.

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).
