A new mixed signal module fully integrates power, control functions, and drive circuitry into a single 2” x 4”

x 0.48” package. The module provides closed loop speed control of three phase, brushless DC (BLDC)

motors used in a variety of system applications. The OMC506 has been designed with flexibility in mind.

Timing functions and loop parameters can be adjusted to optimize the OMC506 to each customer’s application.

In addition, the OMC506 has been designed into a MP-3T package. This package uses an insulated metal

substrate, thereby, isolating the module’s electronics from chassis while providing the necesssary thermal

interface for proper performance. The OMC506 offers a high efficiency, flexible, compact, motion control

system in an industry standard footprint.
