TIDA-00827 is an integrated sensor-based BLDC motor controller reference design for low-power, battery-powered brushless DC motor applications. The 8 to 35V operating voltage range supports 3S to 6S lithium polymer battery power supplies. Specific applications include camera heads, low-power fans and robots. The motor controller consists of the MSP430G2353 16-bit, ultra-low power microcontroller and the DRV8313 highly integrated 2.5A triple half-bridge driver. The MSP430G2353 utilizes Hall sensor-based communication feedback to provide the correct drive voltage to the motor through the DRV8313. Onboard potentiometers and buttons provide a simple interface to control the motor.
