HIGH  
1VCC represents the generated voltage between the VCC pin and the GND pin.  
2Relative 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).  
3Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.  
3Measured with and without bypass capacitor of 0.01 μF. Adding a larger bypass capacitor causes longer Power-On Time.  
5POS is defined as true only with a VCC slew rate of 25 mV/μs or greater. Operation with a VCC slew rate less than 25 mV/μs can permanently harm  
device performance.  
6POS is undefined for t > ton or BRP < B < BOP
