The DRV8839DSSR is an integrated circuit (IC) component that belongs to the motor drivers family. Designed by Texas Instruments, this versatile component is widely used in various robotic and motion control applications. It provides bidirectional control for brushed DC motors or other loads, making it a reliable choice for driving motors in both forward and reverse directions.
The DRV8839DSSR offers several key features that enhance its performance and flexibility. Firstly, it operates over a wide voltage range of 0 V to 11 V, allowing it to work with various motor types and power supplies. Moreover, it has a maximum output current rating of 1.2 A, enabling it to handle motors with higher power requirements.
To simplify motor control, this IC incorporates two independent H-bridge channels, each capable of driving a single motor. These channels can be combined to drive a stepper motor by connecting both outputs in parallel. The DRV8839DSSR supports up to 1/16 microstepping resolution, giving precise control over motor movements.
Another notable feature of the DRV8839DSSR is its integrated protection circuitry. It includes thermal shutdown and over-current protection, safeguarding the IC and connected motors from damage due to excessive heat or current. Additionally, the component offers built-in shoot-through protection, preventing simultaneous activation of high- and low-side switches, which could lead to short circuits.
