Sensorless, Brushless DC Motor Driver IC

Texas Instruments Incorporated 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 percent, allowing designers to create smaller, sleeker, more innovative designs. 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. Features include extended battery life, low power, accelerated time to market, reduced board space and ease of use, and efficient and quiet drive.

The DRV10963EVM evaluation module (EVM) is a cost-effective, sensorless solution for running a 3-phase BLDC motor. The EVM includes a TLC555 low-power timer configured to supply pulse width modulation (PWM), and a potentiometer to adjust the speed of the motor.

The DRV10963 is available now in a thermally efficient, 10-pin 3x3 mm USON package with an exposed thermal pad for a suggested retail price of US $0.49 in 1,000 unit quantities.
