Three-Phase logic Truth Table (IN = [H] indicates a condition in which IN+ > IN–.)
S/S pin
N1,N2 pin
When S/S and PWMIN pins are not used, set the input to the L level voltage.
For HP output, pulsed output of Hall input IN1 (1-Hall output), 1/2 division output of 1 Hall, or synthetic output of three
phases of Hall input (three-Hall synthetic output) may be selected.
