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).
3IZSUPPLY(max) = ICCL(max) + 3 mA.
4Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
5Measured with and without bypass capacitor of 0.01 μF. Adding a larger bypass capacitor causes longer Power-On Time.
6POS 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.
7POS is undefined for t > ton or BRP < B < BOP.
