Texas Instruments DRV8837 1.8A Low Voltage Brushed DC Motor Driver
Texas Instruments DRV8837 1.8A Low Voltage Brushed DC Motor Driver is the world's smallest 1.8A brushed DC motor driver. TI DRV8837 comes in a tiny, 2 x 2mm 8-pin WSON package, a 75% reduction in size versus the next nearest competitor, enabling smaller, sleeker designs. At 280mΩ, the RDS(ON) is half that of competing devices, supporting 1.8A continuous output current with excellent thermal performance. The small package size, low RDS(ON), and ultra-low 35nA sleep current make DRV8837 DC Motor Driver ideal for portable medical and robotics applications. DRV8837EVM evaluation module demonstrates the capabilities and performance of the DRV8837 motor driver.
