represents the generated voltage between the VCC pin and the GND pin.

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).

Measured without bypass capacitor between VCC and GND. Use of a bypass capacitor results in slower current change.
5
Measured with and without bypass capacitor of 0.01 糉. Adding a larger bypass capacitor causes longer Power-On Time.

POS is defined as true only with a V

slew rate less than 25 mV / 約 can permanently harm
