TI Introduced Three-phase Brushless Motor

Published:2011/9/23 7:32:00 Author:Amy From:SeekIC

Texas Instruments has released the first new integrated three-phase brushless motor pre-drivers. The DRV8301 reduces board space as much as 60 percent as compared to the next closest integrated solution. In addition, the device drives sub-10-A to 60-A external FETs, and offers current scalability, desirable thermal performance and efficiency in brushless DC (BLDC) and permanent magnet synchronous motor (PMSM) applications. It includes a 1.5-A step-down voltage regulator to power the system microcontroller (MCU); two current-sense amplifiers with integrated input and feedback resistors for current measurements; and a SPI interface for device configuration from the MCU.

Texas Instruments designs and manufactures analog, digital signal processing and DLP chip technologies that help customers deliver consumer and industrial electronics products with greater performance, increased power efficiency, higher precision, more mobility and better quality. From affordable mobile phones that connect more people, to classroom projectors that support remote learning, to prosthetic devices that provide greater confidence, flexibility, and freedom – TI technology powers new ideas and inspires better solutions.
