POS  
ton ≤ ton(max); VCC slew rate ≥ 25 mV/µs  
HIGH  
1Relative 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 field (or a weaker north polarity field, if present).  
2The maximum value for IZ(supply) is equal to ICC(L)MAX + 3 mA.  
3The 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.  
4The value of ton depends on the value of the bypass capacitor, if one is used, with greater capacitances resulting in longer ton  
A VCC slew rate less than 25 mV/µs affects device performance, both while powering-on and while running. For ton > ton(max), and BRP < B < BOP, POS  
is undefined.
