DRV8871DDAR Typical application Circuitry

DRV8871DDAR

The is part of Texas Instruments' DRV8871 series, known for its specialized motor driver solutions primarily aimed at controlling brushed DC motors. This series is lauded for its ability to deliver efficient motor driving in various applications, including industrial tools, automotive applications, and consumer electronics. The distinguishes itself with its single H-bridge design, allowing it to control one DC motor with functionalities like forward, reverse, braking, and speed control. It also features advanced protection capabilities such as overcurrent protection, thermal shutdown, and a wide operating voltage range, making it a robust choice for diverse motor control scenarios.

1. Power Supply Arrangement: The DRV8871DDAR operates within a voltage range of 6.5V to 45V. Connect the VM pin to an appropriate power source within this range. To maintain a consistent power supply and to reduce noise, a decoupling capacitor near the VM pin is recommended.

2. Grounding Approach (GND Pin): The device includes a Ground (GND) pin, which should be connected to the system's ground. This connection is essential for the stability and optimal functioning of the DRV8871DDAR.

3. Motor Connection (OUT1 and OUT2 Pins): The DRV8871DDAR controls the motor via the OUT1 and OUT2 pins. These should be connected to the two terminals of a DC motor, allowing control of motor direction and speed.

4. Input Signal Integration (IN1 and IN2 Pins): The IN1 and IN2 pins are designated for receiving input control signals that determine the motor's operation. Connect these to the output controls from a microcontroller or another control system.

5. Enable Functionality (nSLEEP Pin): The DRV8871DDAR features an nSLEEP pin for enabling or disabling the motor driver. Connect this pin to a high logic level for operation, or to a low logic level for sleep mode.

6. Fault Indication (nFAULT Pin): The nFAULT pin is an open-drain output that indicates fault conditions like overcurrent or thermal overload. This pin should be interfaced with a microcontroller for effective fault detection and management.

7. PCB Layout Design: Designing the PCB for the DRV8871DDAR requires careful management of motor control paths and the separation of power and signal traces to minimize electromagnetic interference.

8. Thermal Management and Protective Measures: Considering the DRV8871DDAR's power handling capacity, implementing thermal management solutions and protective components such as resistors and capacitors is advisable for enhanced performance and durability.

In summary, the DRV8871DDAR is an efficient and reliable motor driver, ideal for controlling brushed DC motors in various applications. Ensuring proper connections for the power supply, grounding, motor control, input signals, enable function, and fault indication, combined with a well-organized PCB layout and thermal management, are crucial for optimizing the performance of the DRV8871DDAR in motor control systems.
