DALLAS, May 22, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NASDAQ: TXN) today 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 driverthat 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. For more information
or to place an order, visit www.ti.com/drv10963-pr.

Key features and benefits of the DRV10963:

  oExtended battery life: 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 percent compared to nearest competition in fans and portable,
    battery-powered personal health care and grooming devices, including
    electric razors and toothbrushes. It provides the lowest quiescent current
    to further extend battery life – 15 uA compared to 30 uA for the closest
    competitor.
  oLow power: 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 a versatile analog comparator, allowing
    wake-up from low-power mode to active mode in less than 1 µs.
  oAccelerated time to market: Integrated commutation logic eliminates code
    development, while advanced on-chip protection reduces design complexity
    and improves system reliability. This cutts development time from months
    to minutes.
  oReduced board space and ease of use: Single-chip solution slashes board
    space by 80 percent compared other discrete solutions, and integrated
    power MOSFETs simplify layout.
  oEfficient and quiet drive: Pure sinusoidal outputs provide efficiency and
    noise-free operation. 

Tools and support
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.

Support is available on the Motor Driver Forum in the TI E2E^TM Community,
where engineers can ask questions and get answers from TI experts.

Package, availability and pricing
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.
