TI公司的DRV10983-Q1是集成了功率MOSFET的12V/24V汽车三相无传感器BLDC马达驱动器,连续驱动电流高达2A.满足汽车规范AEC-Q100如–40℃ 到125℃工作温度,HBM ESD分类Level 1C,CDM ESD分类Level C4A,马达工作电压6.2V-28V,具有过流保护,锁住检测,防电压浪涌(AVS)保护,UVLO保护和热关断保护.主要用在汽车小型泵和风扇,座椅通风风扇,HEV电池冷却风扇和摩托车燃油泵.本文介绍了DRV10983-Q1主要特性,功能框图,应用电路以及评估模块DRV10983-Q1 EVM主要特性,电路图,材料清单和PCB效果图.

The DRV10983-Q1 device is a 3-phase sensorlessmotor driver with integrated power MOSFETs, whichcan provide continuous drive current up to 2 A. Thedevice is specifically designed for cost-sensitive, lownoise,low-external-component-count fan and pumpapplications.

The DRV10983-Q1 device preserves register settingdown to 4.5 V and delivers current to the motor withsupply voltage as low as 6.2 V. If the power supplyvoltage is higher than 28 V, the device stops drivingthe motor and protects the DRV10983-Q1 circuitry.This function is able to handle a load dump conditionup to 45 V.
