V
The V
Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
Power-Up Time is measured without and with bypass capacitor of 0.01 μF, B < B
Guaranteed by characterization and design.
Power-Up State as defined is true only with a V
For t > t
Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north
