The Texas Instruments DRV8834RGET is a fully integrated bipolar stepper motor driver with a built-in power stage and control logic. It drives one bipolar stepper motor or two brushed DC motors using a half-bridge output configuration (4 half-bridges total). The output current rating is 1.5 A continuous, with a supply and load voltage range spanning 2.5 V to 10.8 V — covering common battery chemistries and regulated rails from 3.3 V to 5 V nominal. Step resolution is programmable from full-step down to 1/32 microstepping, giving the designer a choice between smooth low-speed motion and higher torque at speed without external indexer logic.
Housed in a 24-VFQFN exposed-pad package (24-VQFN 4x4 mm), the DRV8834RGET is a surface-mount device.
Active production and compliance
The base product number is DRV8834; the RGET suffix denotes the specific package and tape-and-reel / cut-tape carrier options.
