Brushless DC motor driver

12 June 2013 Analogue, Mixed Signal, LSI

Texas Instruments released a new sensorless, brushless DC (BLDC) motor driver designed for high efficiency and low noise, which requires a low external component count of only one capacitor. The DRV10963 is a 5 V, 3-phase driver that includes integrated commutation logic, which enables instant motor spin with no code development, while its 180-degree pure sinusoidal outputs provide an efficient and quiet drive. Low operating range of 5,5 to 2,1 V, low RDS(ON) of less than 1,5 Ω and ultra-low sleep currents extend battery life. The IC utilises a 16-bit MSP430G2452 Value Line MCU with built-in timers, up to 16 I/O touch-sense enabled pins, built-in communication and a versatile analog comparator, allowing wake-up from low-power mode to active mode in less than 1 μs.
