TI Introduces Small 1.8-A Brushed DC Motor Driver for Battery Powered Applications

Texas Instruments Inc. (TI) expanded its growing family of low-voltage DRV8x motor drivers with the industry's smallest 1.8-A brushed dc motor driver. The DRV8837 is 75 percent smaller than the nearest competitor, enabling smaller, sleeker, more innovative system design. It also extends battery life and improves thermal performance in battery-powered or low-voltage motion control applications by reducing RDS(ON) by 50 percent and sleep current by 75 percent, compared to existing devices.

Low RDS(ON) of 280mΩ and an ultra-low sleep current as low as 35nA improve thermal performance and extend battery life in applications such as toys, gas or water smart meters, electronic locks, micro printers and cameras. Separate logic and motor supplies improve performance in battery powered applications during start up and stall conditions. A 1.8 to 11V operating range supports up to 6-stack alkaline or 2-stack Li-ion battery pack applications. A tiny 2 x 2mm WSON package enables smaller, sleeker design. Over-current, over-temperature, shoot-through and under-voltage protection increase system reliability and reduce design complexity.
