OM9373SP General Description


The OM9373 is one of a series of versatile, integrated three-phase brushless DC motor controller/driver subsystems housed in a 43 pin power flat-pack. The OM9373 is best used as a two quadrant speed controller for controlling/driving fans, pumps, and motors in applications which require sm-all size.  Many integral control features provide the user much flexibility in adapting the OM9373 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.
