•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.
