TI Introduces Sensorless, Brushless DC Motor Drive

Texas Instruments has expanded its sensorless, brushless DC (BLDC) motor driver portfolio with a new device 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 sensorless BLDC motor driver that simplifies layout and reduces board space by 80%, the company says. It 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.

The low operating range of 5.5 to 2.1 V, low RDSON of less than 1.5 ohm and ultra-low sleep currents extend battery life up to 25%. It utilizes a 16-bit, ultra-low power MSP430G2452 Value Line microcontroller with built-in timers, up to 16 I/O touch-sense enabled pins, built-in communication and an analog comparator, allowing wake-up from low-power mode to active mode in less than 1 µs.
