Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north magnetic
polarity; therefore greater B values indicate a stronger south polarity
fi
eld (or a weaker north polarity
fi
eld, if present).

The maximum value for I

is equal to I
CC(L)MAX
+ 3 mA.

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.

The value of t
on
depends on the value of the bypass capacitor, if one is used, with greater capacitances resulting in longer t
