Closed Loop Speed Controller For
3-Phase Brushless DC Motor
MP-3T Package
OMC506
Description:
The OMC506 is an integrated, high density, three phase
Brushless DC (BLDC) motor, speed controller housed in a
MP-3Tpackage. The OMC506 contains the power, driver
and control electronics to adjust timing functions and speed
control loop parameters to optimize the controller for each
application. The electronics contained in the OMC506 are
assembled using mixed process technologies: surface
mount components on a printed circuit board and chip &
wire on an Insulated Metal Substrate.This combination
offers small size, excellent thermal characteristics and
electrically isolated heat sink.

Current Limit
The OMC506 provides outputs from the internal current sense resistor (pin 7& 8). These outputs can be
directly wired to the C.S. +, C.S.- (pin 28 & 27) inputs. The outputs can also be used in external current limit
circuitry. Figure 1 shows a typical connection of the OMC506’s current limit circuitry.
Figure 1 - Current Limit Circuitry
Over Temperature Protection
The OMC506 has been designed with an internal over temperature protection circuit. The circuit provides a
diagnostic in the event an over temperature condition occurs in the power stage. The circuit normally outputs
a voltage level < 0.5Vdc. When the power stage reaches 140°C, the VOUT (pin19) will rise to +15Vdc. The
OMC506 also outputs a control function for this circuitry. A logic “0” at pin 18 will disable the over temperature
circuit and a logic “1” will force VOUT to go high. The over temperature circuitry has been designed to interface
with a system controller. The system controller can act on the pretense of an over temperature and shut the
OMC506 down. The system controller may opt to over ride the over temperature flag and disable the circuit
over temperature circuitry. In addition, the system controller can force the VOUT high as part of a built in test
(BIT) feature at the system level. The over temperature circuitry will reset when the power stage has cooled to
130°C. Finally, an internal diode can be jumpered causing the temperature circuitry to latch on trip, requiring
a power off reset.
