*1: When the magnetic flux density to the IC becomes larger than Bop, the IC goes into an on-state and outputs a low signal (V_OUT=Low) at the
leading edge of the next “tawake” pulse.
*2: When the magnetic flux density to the IC becomes lower than Brp, the IC goes into an off-state and outputs a high signal (V_OUT=High) at the
leading edge of the next “tawake” pulse.
During the other periods, the previous state is maintained.
