Note) “H” for FR represents a voltage of 2.75V or greater ; “L” represents a voltage of 2.25V or lower (at VCC = 5V).
Note) Input “H” for all input represents that (+) is higher than each phase input (-) by 0.01V or greater ; input “L”
represents that (+) is lower than each phase input (-) by 0.01V or greatre.
Note) Since this drive scheme is the 180
° energizing scheme, phases other than Sink, Source phases are not turned OFF.
