Function
Outputs. These are push-pull
outputs.
Duty control is applied to the
UH, VH, and WH pins. Internal
50kΩ leakage protection
resistors between the outputs
and ground are provided to
protect against output leakage
in standby mode.
Hall effect sensor inputs from
each motor phase.
The logic high state
corresponds to the state where
IN+ > IN-. If input is provided
from a Hall IC, the common
mode input range can be
expanded by biasing either the
+ or - input.

HP
Hall signal single-phase
output. (This pin is an
open-collector output.) This pin
outputs a signal that is inverted
from the signal formed from
the IN3 input.

CEG
Rotation pulse edge detection
input.
(This input is used by the
one-shot multivibrator circuit.)
Insert a capacitor between this
