Note 1: No measurements are performed for any values listed in the conditions column as design targets.
Note 2: The torque ripple correction factor is calculated using the Rf voltage waveform as follows.

Note: ‘‘H’’ in the FR column represents a voltage of 2.75 V or
more; ‘‘L’’ represents a voltage of 2.25 V or less.
(At VCC = 5 V)
Note: ‘‘H’’ in the Hall input columns represents a state in
which ‘‘+’’ has a potential which is higher by 0.01 V or
more than that of the ‘‘−’’ phase inputs.
Conversely, ‘‘L’’ represents a state in which ‘‘+’’ has a
potential which is lower by 0.01 V or more than that of
the ‘‘−’’ phase input.
Note: Since 180° energized system is used as the drive system, other phases than the sink and source phases are turned off.
