In summary, STMicroelectronics has a portfolio of products designed to interface a system architecture with the power stage of a motor controller. This includes motor bridge controllers with control, diagnostics, and system protection capability for brushed, brushless, and stepper motor applications. System interface features allow application in distributed architectures, while an SPI interface reduces the microcontroller and software requirements to safely control various motor technologies. Other features are H-bridge drives are active recirculation, stall detect, BEMF detect, and charge pump outputs for reverse battery protection. Integrated H-bridges are available with power stage ratings from 19 mΩ to 280 mΩ RDS(on). This integrated power stage allows a very small footprint for higher current applications.
