Three-Phase Logic Truth Table (“IN = ‘H’” indicates the state where IN+ > IN-.)
S/S Pin
N1 and N2 Pins
If either the S/S or PWMIN pins are not to be used, the unused pin input must be set to the low-level voltage.
The HP output can be selected (by the N1 and N2 settings) to be one of the following four functions: the IN1 Hall input
converted to a pulse output (one-Hall output), the one-Hall output divided by two or the three-phase output synthesized
from the Hall inputs (three-Hall synthesized output).
