Three-Phase Brushless/PMSM (Permanent Magnet Synchronous Motor) High Current Motor Control Solution (TIDM-THREEPHASE-BLDC-HC)
This reference design demonstrates a motor control solution for spinning three-phase brushless DC (BLDC) and brushless AC (BLAC) - often referred to as “permanent magnet synchronous (PMSM)” - motors featuring the C2000™ Piccolo™ microcontroller and the DRV8302 three-phase motor driver. It provides three half-bridge drivers, each capable of driving two N-type MOSFETs, one for the high side and one for the low side. It supports up to 2.3A sink and 1.7A source peak current capability and only needs a single power supply with a wide range from 8V to 60V. The reference design features a high-performance, power-efficient, cost-effective platform that speeds development for quicker time to market. Applications include CPAP and pumps, e-bikes, e-scooters, medical pumps and drills, power tools, and robotics. This reference design is a high-performance, power-efficient, cost-effective sensorless field-oriented control (FOC) and sensored/sensorless trapezoidal commutation platform that speeds development for quicker time to market. This reference design is based on the DRV8302 evaluation kit.
