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.
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.
