Texas Instruments announced eight new devices for their DRV8x motor driver family. The new TI motor drivers are DRV8813, DRV8825, DRV8829, DRV8814, DRV8840, DRV8841, DRV8842, and DRV8843. The new DRV8x motor drivers feature RDSon as low as 100 milliohms and microstepping options up to 256 microsteps and greater with an external microcontroller or up to 32 microsteps with an on-chip indexer. The DRV8825 DRV8x motor driver is priced at $2.40 (1,000 unit quantities). The other seven new drivers are priced at $2.25 (1,000-unit). The eight new devices are available now in a 9.7 mm x 6.4 mm HTSSOP package.
Texas Instruments (TI) announced the DRV8412 evaluation kit (DRV8412-C2-KIT) for spinning motors. The DRV8412 evaluation platform for spinning motors includes all of the hardware and software needed to spin two brushed DC motors or a single stepper motor. The DRV8412-C2-KIT speeds development time for brushed DC and stepper motors running up to 6 A continuous/12 A peak at 50 V. The kit is for ideal medical pumps, gate openers, stage lighting, textile manufacturing tools, and industrial or consumer robotics. The DRV8412-C2-KIT is available now for $199 (price includes CCStudio IDE with no compiler or memory limitations).
