The DRV8871DDAR is an integrated circuit (IC) component designed for motor control applications. Manufactured by Texas Instruments, this IC offers several key features that make it suitable for various motor control systems.
One notable feature of the DRV8871DDAR is its ability to drive brushed DC motors with a wide range of operating voltages, typically ranging from 3.6V to 36V. This voltage range allows the IC to be used in a wide variety of applications, including robotics, automotive, and industrial systems.
Another important feature of the DRV8871DDAR is its high current drive capability. It is capable of supplying up to 3.6A of continuous current to each motor channel, making it suitable for driving motors with higher power requirements. Moreover, the IC has a peak current limit of up to 6.5A, allowing it to handle brief high-current demands without damaging the circuit.
The DRV8871DDAR also includes a configurable PWM (Pulse Width Modulation) control interface. This feature allows users to adjust the motor speed and direction by varying the duty cycle of the PWM signal. The IC supports both forward and reverse motor rotation, enabling bidirectional motor control.
For protection and safety, the DRV8871DDAR incorporates various integrated protection features. These include overcurrent protection, undervoltage lockout, and thermal shutdown. These protections help prevent damage to the IC and the connected motor in case of fault conditions
