DRV8821DCAR Typical application Circuitry

DRV8821DCAR

The DRV8821DCAR is part of Texas Instruments' DRV8821 series, a line of motor drivers that are specifically tailored for controlling stepper motors. This series is widely recognized for its precision and efficiency, making it a preferred choice in various applications such as automation, office equipment, and consumer electronics. The DRV8821DCAR is noted for its dual full-bridge design, capable of driving one bipolar stepper motor or two brushed DC motors, and includes advanced features like microstepping support, overcurrent protection, and thermal shutdown.

1. Power Supply Arrangement: The DRV8821DCAR operates within a voltage range of 8.2V to 45V. The VM pin should be connected to a power source within this range. A decoupling capacitor near the VM pin is suggested for power supply stability and noise reduction.

2. Grounding Scheme (PGND and AGND Pins): The device features separate Power Ground (PGND) and Analog Ground (AGND) pins. To guarantee the DRV8821DCAR's best performance and noise reduction, both PGND and AGND should be connected to the system's ground.

3. Motor Phase Connections (OUT1A, OUT1B, OUT2A, OUT2B Pins): The DRV8821DCAR controls a stepper motor through its OUT1A, OUT1B, OUT2A, and OUT2B pins. These should be connected to the respective coils of a bipolar stepper motor.

4. Input Signal Control (AIN1, AIN2, BIN1, BIN2 Pins): The AIN1, AIN2, BIN1, and BIN2 pins receive input signals that govern the stepper motor's operation. Connect these to the output controls from a microcontroller or another control system for managing the stepping sequence.

5. Microstepping Configuration (DECAY, MODE Pins): The DRV8821DCAR includes DECAY and MODE pins for microstepping and current decay mode control. These pins should be set up according to the desired microstepping resolution and current decay profile.

6. Current Sensing (ISEN1, ISEN2 Pins): The ISEN1 and ISEN2 pins are used for current sensing, essential for managing the current in the motor coils. Connect these to current sensing resistors for accurate current control.

7. Fault Indication (nFAULT Pin): The nFAULT pin is an open-drain output that signals fault conditions like overcurrent or thermal overload. For defect monitoring, connect this pin to a microcontroller input.

8. PCB Layout Design: When designing the PCB for the DRV8821DCAR, it's crucial to manage high-current paths effectively and separate power and signal traces to reduce electromagnetic interference.

9. Thermal Management and Protection: Given the DRV8821DCAR's power handling capabilities, implementing thermal management solutions such as heatsinks and protective components like resistors and capacitors is recommended for enhanced performance and durability.

In summary, the DRV8821DCAR is a highly capable motor driver, perfect for controlling bipolar stepper motors or two brushed DC motors in a variety of applications. Proper connections for the power supply, grounding, motor phase, control inputs, microstepping, current sensing, and fault indication, along with thoughtful PCB design and thermal management, are essential for optimizing the performance of the DRV8821DCAR in your motor control projects.
