4.4V to 30V, 15A, high-performance brushless DC propeller controller reference design

TIDA-00643

Overview

The TIDA-00643 reference design is a 4.4 to 30 V brushless DC motor controller for high power propeller, fan and pump applications. It uses Texas Instruments' DRV8305 brushless DC motor gate driver, CSD17573Q5B 30V NexFET power MOSFET, TPD4E05U06 TVS protection integrated circuit, C2000 motor control MCU, and LMR16006 3.3 V buck converter. It uses InstaSPINTM-FOC for sensorless magnetic field positioning control and controls motor speed via an external reference signal from a central controller. The design aims to create an efficient and high-power BLDC motor system.

Issues with changing interrupt vector in freeRTOS?
I plan to use 0x08000000 - 0x08001FFF for IAP, and start running the freeRTOS small system from 0x08002000. However, freeRTOS runs at 0x08000000 by default. After I tried to change the interrupt vecto
How to connect ATtiny2313 (AVR) and MC68HC908AP (Freescale) via serial port
As the title says. Serial port settings: 9600 bps, 8bits, 1 stop bit, no parity. Pull-up resistors are used on MC68HC908AP (resistance value unknown). No pull-up resistors are used on ATtiny2313. I ha
