TI公司的DRV10983是三相无传感器BLDC马达驱动器,集成了功率MOSFET,连续驱动电流高达2A(峰值电流3A),I2C接口,可通过PWM,模拟或I2C输入直接进行控制,输入电压范围8-28V,具有过流保护,锁住检测,电压浪涌保护,UVLO保护和热关断保护.主要用在电风扇和HVAC.本文介绍了DRV10983主要特性,框图和应用电路,以及30W BLDC马达驱动参考设计TIDA-00652主要特性,框图,电路图和材料清单与PCB设计图.

DRV10983 is a three-phase sensorless motor driverwith integrated power MOSFETs, which can providecontinuous drive current up to 2 A. The device isspecifically designed for cost-sensitive, low-noise/lowexternal component count applications.

The DRV10983 uses a proprietary sensorless controlscheme to provide continuous sinusoidal drive, whichsignificantly reduces the pure tone acoustics thattypically occur as a result of commutation. Theinterface to the device is designed to be simple andflexible. The motor can be controlled directly throughPWM, analog, or I2C inputs. Motor speed feedback isavailable through either the FG pin or I2C.
