Design target value*2
Notes : 1. The torque ripple correction ratio is determined as follows from the Rf voltage waveform.
2. Parameters that are indicated as design target values in the conditions column are not tested.

Note: Since the drive technique adopted is a 180° technique, phases
other than the sink and source phase do not turn off.
Note: In the FR column, “H” refers to a voltage of 2.75 V or higher, and “L” refers
to 2.25 V or lower (when VCC = 5 V.)
Note: In the Hall input column, “H” refers to the state in the corresponding phase
where the + input is at a potential at least 0.01 V higher than the – input,
and “L” refers to the state where the – input is at a potential at least 0.01 V
higher than the + input.
