Brushless DC (BLDC) motor drivers – Design & development
This design is a 4.4 to 30 V brushless DC motor controller for high power drone, quadcopter, propeller, fan, and pump applications. It uses TI’s DRV8305 brushless DC motor gate driver, 30V NexFET power MOSFETs, TVS protection IC, C2000 motor control MCU, and LMR16006 3.3 V buck converter.
This design is a power stage for brushless motors in battery-powered garden and power tools rated up to 1 kW, operating from a 10-cell lithium-ion battery with a voltage range from 36 to 42 V. The design uses 60V, N-channel NexFETsTM featuring a very low drain-to-source resistance of 1.8 mΩ.
This reference design is a singled-layered, cost-effective, small-form-factor, three-phase sinusoidal motor drive for sensored BLDC fan motors specified up to a maximum current of 1 A RMS at 18 V maximum. The unique, single-sided design helps to bring down the system cost.
Three-phase brushless DC motor drive designed to operate in 12-V automotive applications.The board is designed to drive motors in the 200-W range and handle currents up to 20A.Utilizing either sensorless operation or external Hall Effect sensors provides the flexibility to adapt to many motors.
