Sensorless, Brushless DC Motor Drivers
Texas Instruments (TI) (Dallas, TX) (NASDAQ:TXN) has introduced two 3-phase, brushless DC (BLDC) motor drivers that allow designers to spin motors in minutes rather than months. Traditional BLDC motor designs require five to 10 components, along with firmware. The sensorless 5-V, 680-mA DRV10866 and the 12-V, 1.5-A DRV11873 cuts this component count to one with no firmware required, significantly reducing board space and system costs, while helping customers speed their time to market. Features include:
- A single motor driver that eliminates the need for external gate drivers, inverters, position detection, and feedback.
- A microcontroller (MCU) and firmware to cut board space, system cost, and development time.
- TI InstaSPIN-FAN motor solutions.
- An operating voltage range of 1.65 to 5.5 V.
- A low quiescent current of 5 uA.
- Over-current, over-temperature, shoot-through, and under-voltage lock-out on-chip protection
