Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north magnetic
Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
Measured with and without bypass capacitor of 0.01 μF. Adding a larger bypass capacitor causes longer Power-On Time.
POS is defi ned as true only with a V
POS is undefi ned for t > t
Relative values of B use the algebraic convention, where positive values indicate south magnetic polarity, and negative values indicate north magnetic
