Three-Phase Brushless DC Motor Driver
Texas Instruments
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.
