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 flatpack.

The OM9373 is best used as a two quadrant speed controller for controlling/driving fans, pumps, and motors in applications which require small size. Many integral control features provide the user much flexibility in adapting the OM9373 to specific system requirements.
