DESCRIPTION
The OM9369CM is one of a series of versatile, integrated three-phase brushless DC motor
controller/driver subsystems housed in a CERMOD TM. The OM9369CM 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 OM9369CM can effectively control range from
fractional HP up to several HP. The OM9369CM is ideal for use on DC distribution busses up to and
including 270Vdc. Many integral control features provide the user much flexibility in adapting the
OM9369CM to specific system requirements.
The small size of the complete subsystem is ideal for aerospace, military, and high-end industrial
applications.

SPECIFICATION NOTES:
1. All parameters specified for Ta = 25°C, Vcc = 15Vdc, Rosc = 75KΩ (to Vref), Cosc = 1800 pF, and all Phase Outputs unloaded (Ta ~ Tj). All negative currents shown
are sourced by (flow from) the pin under test.
2. Either ISH or ISL may be driven over the range shown.
3. Bold parameters tested at -55°C, 25°C, 125°C.
