DRV8251ADDAR Typical application Circuitry

DRV8251ADDAR

The DRV8251ADDAR is a key part of the DRV8251A series, a collection of integrated motor drivers developed by Texas Instruments. This series is well-known for its ability to operate brushed DC motors effectively. The DRV8251ADDAR, in particular, is designed to cater to a range of applications such as home appliances, printers, and other motor-driven equipment. It stands out for its robust performance, versatility, and integration of multiple features like overcurrent protection and thermal shutdown.

1. Power Supply Attachment: The DRV8251ADDAR requires a power supply ranging typically from 8.2V to 45V. Within this voltage range, the VVM pin must be linked to a power supply. To maintain a stable power supply and reduce noise, it's advisable to place a decoupling capacitor near this pin.

2. Grounding Considerations (PGND and AGND Pins): The DRV8251ADDAR features separate grounds for power (PGND) and analog/digital circuits (AGND). It's crucial to connect both PGND and AGND pins to the system's ground for optimal performance and noise reduction.

3. Motor Connection (OUT1 and OUT2 Pins): The motor's terminals should be connected to the OUT1 and OUT2 pins of the DRV8251ADDAR. This setup allows the chip to control the motor's operation.

4. Input Signal Interface (IN1 and IN2 Pins): The IN1 and IN2 pins are used for receiving input signals that control the motor's direction and operation. These should be connected to the output of a microcontroller or another control circuit.

5. PWM Control (PWM Pin): The PWM pin allows speed control of the motor through pulse width modulation. Connecting this pin to a PWM output from a microcontroller enables precise control over the motor's speed.

6. Current Sensing (ISEN Pin): The ISEN pin is used for current sensing and should be connected to a shunt resistor or another current sensing device to monitor the motor's current draw.

7. Fault Indication (nFAULT Pin): The nFAULT pin is an open-drain output that indicates fault conditions like overcurrent or thermal shutdown. It should be connected to an input pin on a microcontroller to detect and respond to any faults.

8. PCB Design and Layout: When designing the PCB for the DRV8251ADDAR, it is important to ensure that the traces carrying high currents are wide enough to handle the load. Additionally, keep the power traces and signal traces separate to minimize interference.

9. Thermal Management and Protective Measures: Considering the power capabilities of the DRV8251ADDAR, implementing adequate thermal management, such as heatsinks or thermal vias, is essential. Furthermore, adding protective components like resistors or capacitors can provide additional safeguarding against electrical transients or other adverse conditions.

To sum up, the DRV8251ADDAR is an advanced motor driver suitable for driving brushed DC motors in a wide array of applications. Ensuring proper connections for power supply, grounding, motor, control inputs, PWM, current sensing, and fault indication, along with thoughtful PCB design and thermal management, is essential for harnessing the full capabilities of the DRV8251ADDAR in motor control applications.
