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.
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.

APPLICATIONS
Start-Up Conditions
The OM9369 3-phase brushless DC motor controller/
driver is designed to drive fractional to integral
horsepower motors. To ensure proper operation, it is
necessary to ensure that the high-side bootstrap
capcitors are charged during initial start-up. However,
the method(s) used to ensure this may be dependant
upon the application. For example, some applications
may only require that OV_COAST (pin 17) be
connected to ground, either via a hardwire connection
or via a switch (Enable/Disable), before applying Vcc.
When Vcc is applied, the controller/driver is forced
into brake mode for approximately 200µs (all high-
side drivers are disabled and all low-side drivers are
enabled).
This may not be adequate for other applications;
while maintaining a constant speed command, (above
zero), RC_BRAKE (pin 16) may have to be momentarily
connected to ground via a switch, either manually or
electronically (ref. Figure 1). Note that with the
component values shown in Figure 1, RC_BRAKE
is pulled for low for approximately 300ms after
applying Vcc at pin 1.
