V
CC
represents the generated voltage between the VCC pin and the GND pin.
2
The V
CC
slew rate must exceed 600 mV/ms from 0 to 3 V. A slower slew rate through this range can affect device performance.
3
Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
4
Power-Up Time is measured without and with bypass capacitor of 0.01 糉. Adding a larger bypass capacitor would cause longer Power-Up Time.
5
Guaranteed by characterization and design.

Power-Up State as defined is true only with a V

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 field (or a weaker north polarity field, if present).
