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.
