Next zero crossing switches the output ON (VQ=LOW). ∆BHYS=|∆BENOP-∆BENRP| Outside of a permanent magnet the magnetic induction (=flux density) points from north to the south pole. It is common to define positive flux if the south pole of a magnet is on the branded side of the IC. This is equivalent to the north pole of the magnet on the rear side of the IC.
