Note: “H” in the FR column represents a voltage of 2.75V or more. “L” represents a voltage of 2.25V or less.
(At VCC = 5V)
Note: “H” under the Hall Input columns represents a state in which “+” has a potential which is higher by 0.01V or
more than that of the “-” phase inputs. Conversely “L” represents a state in which “+” has a potential which is
lower by 0.01V or more than that of the “-” phase inputs.
Note: Since a 180
° energized system is used as a drive system, other phases than the sink and source are not OFF.
