Three-Phase Brushless DC Motor Driver

Description

The Three-Phase Brushless DC Motor Driver reference design is a 10A: 3-phase brushless DC drive stage based on the DRV8301 pre-driver and CSD18533Q5A NextFET™ power MOSFET. It has three low side current sense amps (two internal to DRV8301: one external). The design also leverages a 1.5A step down buck converter: is fully protected with short circuit: thermal: and shoot-through protection: and is easily configured via a SPI interface. It is ideal for sensorless: brushless control techniques and drive stage design.

Features
  • Complete brushless DC drive stage in ultra-small form factor (2.2 x 2.3”)Supports up to 14A peak: 10A continuous current outputSupports voltage and current feedback for InstaSPIN-FOC sensorless control solution3x low side current sense amps: 6x Power FETs (Drive stage is fully protected including short circuit: thermal: shoot-through: and under voltage protectionC2000 Piccolo F28027F MCU with InstaSPIN™-FOC technology
