Brushless DC (BLDC) motors are popular in industrial and automotive applications for best system efficiency, longer life and compact design. These applications use a wide range of low voltage input supplies like 5V, 12V, 24V, 36V, 48V DC in industrial and 12V, 24V, 48V in automotive applications. The recent trend of wider adaption to 48V helps in reduction of overall system cost, efficiency improvement while still enabling low-voltage architecture, minimizing safety concerns. Applications like robotics, humanoids, BLDC motor modules, and automotive systems often require integration of electronics in to the motor body for smart motor designs to reduce cabling, EMI and system design complexities.
This application note introduces TI’s latest 3-phase integrated FET BLDC driver DRV8376 (70V, 4.5A peak), and describes how DRV8376 helps to design compact BLDC drives up to 48V applications.
