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 buses up to and including 270Vdc. Many integral control features provide the user much flexibility in adapting the OM9369 to specific system requirements.
