DALLAS, April 12, 2012 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NASDAQ: TXN) today expanded its growing portfolio of highly integrated DRV8x motor drivers with three new low-voltage devices for brushed DC and stepper motors. The DRV8834, DRV8835 and DRV8836 motor drivers provide a wide, low-voltage operating range, low RDS(ON) and ultra-low sleep currents, slashing power consumption as much as 80 percent compared to the nearest competitor to extend battery life, improve thermal performance and increase system reliability. The devices are also highly integrated in an ultra-small package, reducing board space by as much as 95 percent compared to discrete implementations. For more information or to place an order, visit www.ti.com/drv8834-pr.
Ultra-smooth motion profiles: On-chip 32-step microstepping indexer and advanced motion control features on the DRV8834 minimize torque ripple for quiet, ultra-smooth motion in applications such as security video cameras, medical and office automation equipment.
Extended battery life:Low RDS(ON) of 305 milliohms and an ultra-low sleep current as low as 10 nA improves thermal performance and extends battery life in applications, such as toys, e-locks, cameras, point-of-sale printers and smart meters.
Drop in and spin: High level of integration, such as an on-chip indexer and current control loops, provides greater intelligence to reduce design complexity while minimizing microcontroller (MCU) MIPS requirements and software development, speeding time to market compared to discrete solutions.
Reduced board space:Tiny 2-mm x 3-mm package option for the DRV8835 and DRV8836.
Advanced on-chip protection: Over-current, over-temperature, shoot-though and under-voltage lock-out increase system reliability and manufacturing yields.
Tools and support
Evaluation modules (EVMs) are available today to quickly evaluate all three devices. Suggested retail pricing for the DRV8834EVM is US$99. The DRV8835EVM and DRV8836EVM are available for a suggested retail price of US$49, respectively.
Package, availability and pricing
The new DRV8x devices are all available to sample and purchase today. Package, availability and suggested retail pricing are as follows.
Package and availability: 2-mm x 3-mm WSON package available today.
*All prices quoted are based on 1,000-unit quantities.
Drop in and spin with DRV8x motor drivers
DRV8x motor drivers integrate many of the functional blocks needed in a motor system, such as gate drive circuitry, MOSFETs, protection circuitry and current regulation circuitry. DRV8x motor drivers make it easy to drive a wide range of stepper, brushed DC and brushless DC motors in portable and wired applications such printers, video surveillance, fans, pumps, valves, power tools, textile manufacturing machines, e-locks and consumer electronics.
