DRV8870DDAR Typical application Circuitry

DRV8870DDAR

The DRV8870DDAR is part of Texas Instruments' DRV8870 series, recognized for its motor driver solutions specifically designed for brushed DC motors. This series is celebrated for its capability to efficiently drive motors in various applications, including industrial automation, automotive systems, and consumer electronics. The DRV8870DDAR stands out with its single H-bridge design, allowing it to control one DC motor with functionalities such as forward, reverse, braking, and variable speed control. Additionally, it includes advanced features like overcurrent protection, thermal shutdown, and a broad operating voltage range, enhancing its suitability for diverse motor control applications.

1. Power Supply Configuration: The DRV8870DDAR operates within a voltage range of 6.5V to 45V. Connect the VM pin to an appropriate power source within this range. A decoupling capacitor close to the VM pin is recommended to ensure a stable power supply and reduce electrical noise.

2. Grounding Strategy (GND Pin): The device includes a Ground (GND) pin, which should be connected to the system's ground. This connection is crucial for the stability and optimal performance of the DRV8870DDAR.

3. Motor Connection (OUT1 and OUT2 Pins): The DRV8870DDAR controls the motor via the OUT1 and OUT2 pins. These should be connected to the two terminals of a DC motor, enabling control of motor direction and speed.

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

5. Enable Functionality (nSLEEP Pin): The DRV8870DDAR includes an nSLEEP pin for enabling or disabling the motor driver. Connect this pin to a high logic level to enable operation, or to a low logic level for sleep mode.

6. Fault Indication (nFAULT Pin): The nFAULT pin is an open-drain output that signals fault conditions such as overcurrent or thermal overload. Connect this pin to a microcontroller input for effective fault detection and management.

7. PCB Layout Design: When designing the PCB for the DRV8870DDAR, it's important to efficiently route the motor control paths and separate power and signal traces to reduce electromagnetic interference.

8. Thermal Management and Protective Measures: Given the DRV8870DDAR's power handling capabilities, implementing thermal management solutions and protective components such as resistors and capacitors is recommended for enhanced performance and durability.

In conclusion, the DRV8870DDAR is an efficient and reliable motor driver, ideal for controlling brushed DC motors in a variety of applications. Proper connections for power supply, grounding, motor control, input signals, enable function, and fault indication, along with a well-planned PCB layout and thermal management, are key to optimizing the performance of the DRV8870DDAR in your motor control projects.
