DRV8803DW Typical application Circuitry

DRV8803DW

The DRV8803DW is a notable stepper motor or brushed DC motor driver IC. To harness the capabilities of the DRV8803DW, proper circuitry and pin connections are essential. Here's a comprehensive guide to establishing those connections:

1. Power Connections: For powering the DRV8803DW, link the VM pin to your motor supply voltage. The V3P3OUT pin provides an output voltage of 3.3V, which can be used by external components if necessary. The VDD pin should be connected to a 3.3V logic supply, and always ensure that the PGND and AND pins are tied to the system ground.

2. Motor Outputs: The DRV8803DW comprises two H-bridge outputs. Connect the OUT1A and OUT1B pins to one winding of your stepper motor and the OUT2A and OUT2B pins to the other winding. If you're using brushed DC motors, each motor can be connected to one set of OUT pins.

3. Control Inputs: Interface the PH/EN1 and PH/EN2 pins of the DRV8803DW to your microcontroller or controlling device. These pins determine the rotational direction and enable or disable the respective motor channels.

4. Fault Reporting: The fault pin on the DRV8803DW provides a fault signal when a problem arises, such as overcurrent. Connect this to your microcontroller to monitor and respond to any potential faults.

5. Decay Mode Setting: The DECAY pin of the DRV8803DW allows you to select the decay mode for current regulation. By setting this pin to logic high or low, or by pulse width modulating it, you can choose the desired decay mode.

6. Current Setting: Attach a resistor from the SENSE pin to ground to set the current regulation threshold for the DRV8803DW. The value of this resistor determines the motor winding current.

7. Thermal Pad: If your DRV8803DW package features a thermal pad, connect it to the ground. This ensures efficient heat dissipation, maintaining the chip within its operational temperature bounds.

8. Voltage Regulator Capacitor: It's beneficial to attach a bypass capacitor between the V3P3OUT and ground to stabilize the internal 3.3V regulator of the DRV8803DW.

To conclude, integrating the DRV8803DW into your system requires careful consideration of each pin and its function. Always consult the specific data sheet for the DRV8803DW to get detailed specifications, recommended component values, and circuit layouts. After setting up the initial connections, it's paramount to test the DRV8803DW under actual operational conditions to ensure peak performance and reliability.
