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.
Note: Since the drive technique adopted is a 180° technique, phases
other than the sink and source phase do not turn off.
