1VCC represents the generated voltage between the VCC pin and the GND pin.
2Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
3Power-Up Time is measured without and with bypass capacitor of 0.01 μF, B > BOP + 10 G. Adding a larger bypass capacitor would cause longer
Power-Up Time.
4Guaranteed by characterization and design.
5Power-Up State as defined is true only with a VCC slew rate of 25 mV/μs or greater.
6For t > ton and BRP < B < BOP, Power-Up State is not defined.

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).
