TI spins motors in minutes with sensorless, brushless DC motor drivers
Integrated motor drivers accelerate product design by eliminating external
components and software development
DALLAS, Feb. 20, 2013
DALLAS, Feb. 20, 2013 /PRNewswire/ -- Texas Instruments Incorporated (TI)
(NYSE:NASDAQ) today 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.
The devices also provide the lowest operating voltage and standby current to
reduce power consumption by up to 75 percent. For more information or to place
an order, visit www.ti.com/drv10866-pr.
Key features and benefits of the DRV10866 and DRV11873
oHighly integrated: Single motor driver eliminates the need for external
gate drivers, inverters, position detection and feedback, along with a
microcontroller (MCU) and firmware, to cut board space, system cost and
oSpins motors in minutes: Utilizes TI InstaSPIN-FAN motor solutions™, a
fully protected robust solution with no coding and very few external
components needed to get motors spinning.
oReduces power consumption by up to 75 percent: Wide operating voltage
range of 1.65 V to 5.5 V and low quiescent current of 5 uA extends the
battery life of portable devices, such as toothbrushes and shavers,
compared to existing solutions.
oFlexibility to add advanced control: Can be combined with a TI MSP430™ MCU
for designs requiring user interface and closed-loop speed control.
oRobust, reliable and fully protected: Advanced on-chip protection,
including over-current, over-temperature, shoot-through and under-voltage
lock-out, increases system reliability.
Tools and support
In addition to the motor driver, the DRV10866EVM and DRV11873EVM evaluation
modules (EVMs) include a simple TLC555 timer, frequency generator output, PWM
input and motor connection to enable fast, code-free motor evaluation. Both
EVMs ship with schematics and gerber files for a suggested retail price of
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 DRV10866 and DRV11837 are available today in a 3-mm by 3-mm SON package
for a suggested retail price of $0.39 and 16-pin TSSOP for suggested retail
price of $0.89, respectively, in 1,000-unit quantities.
