Note: ‘‘H’’ in the FRC column represents a voltage of 2.5 V or
more; ‘‘L’’ represents a voltage of 0.4 V or less.
(At VCC1 =3 V)
Note: ‘‘H’’ in the Hall input columns represents a state in
which ‘‘+’’ has a potential which is higher by 0.02 V or
more than that of the ‘‘–’’ phase inputs.
Conversely, ‘‘L’’ represents a state in which ‘‘+’’ has a
potential which is lower by 0.02 V or more than that of
the ‘‘–’’ phase input.
