Abstract

The MCF831x is an integrated code-free sensorless FOC device, which can be widely used in appliances system, such as residential fans, ceiling fans, air purifiers, washer pumps, and so forth. The high integration and code-free of MC8315 brings great convenience to the development and use of customers, but there are also some common challenges with BLDC design. This application note introduces how to design the hardware of MCF8315 and proposes how to simplify the peripheral design, and provides temperature performance result for design reference.
