Truth Table
•Three-Phase Logic Truth Table (“IN = ‘H’” indicates the state where IN+ > IN–.)
•S/S Pin
•N1 and N2 Pins
Since the S/S pin does not have an internal pull-up resistor, an external pull-up resistor or equivalent is required to set
the IC to the stop state. If either the S/S or PWMIN pins are not 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, the three-phase output synthesized
from the Hall inputs (three-Hall synthesized output) or the three-Hall synthesized output divided by two.
