DESCRIPTION
The OM9369 is one of a series of versatile, integrated three-phase brushless DC motor
controller/driver subsystems housed in a 43 pin power flatpack. The OM9369 is best used as a two
quadrant speed controller for controlling/driving fans, pumps, and motors in applications which require
small size. Typical size brushless DC motors that the OM9369 can effectively control range from
fractional HP up to several HP. The OM9369 is ideal for use on DC distribution busses up to and
including 270Vdc. Many integral control features provide the user much flexibility in adapting the
OM9369 to specific system requirements.
The small size of the complete subsystem is ideal for aerospace, military, and high-end industrial
applications. Two package types provide a broad range of cost and screening options to fit any
application.

SIMPLIFIED BLOCK DIAGRAM
COMMUTATION TRUTH TABLE
This table shows the Phase Output state versus
the state of the Hall-Effect and Direction Inputs.
Please note that the OM9369 Hall-Effect Inputs
are Grey-encoded; that is, only one input is
allowed to change from one input state to
another at a time.
The commutation coding shown reflects HallEffect sensors that are spaced at 120°
mechanical increments. Also, internal
protection logic disables all three Phase
Outputs when the Hall-Effect Inputs are set to
an illegal condition (i.e. all logic low or all logic
high).
