Datasheet: Mx1616 Motor Driver

Arduino digital pins (e.g., 5, 6, 9, 10 for PWM). Outputs (OUT1-4): DC Motors. Example Code

The Mx1616 motor driver datasheet provides detailed information about the IC's features, specifications, and operating conditions. Here is a summary of the key points: Mx1616 Motor Driver Datasheet

: A chip‑level temperature sensor continuously monitors the die temperature. When it exceeds the preset threshold (typically around 150–160°C), the driver shuts down all outputs, protecting the IC from overheating. Once the temperature falls back to a safe level (with hysteresis), the driver automatically resumes operation. Arduino digital pins (e

Typically available in SOP-8 or DIP-8 packages for easy surface-mount or breadboard prototyping. 2. Pinout Configuration and Descriptions Here is a summary of the key points:

| Symptom | Likely Cause | Solution | | :--- | :--- | :--- | | Motor does not spin | STBY pin low | Pull STBY > 2V | | Motor spins only one direction | Broken input pin | Check IN1/IN2 logic levels | | Overheating at 0.5A | PWM frequency too high (>100kHz) or shorted output | Reduce frequency to 20kHz | | IC damaged at 12V | VM exceeded 13.5V (spike from motor braking) | Add a large capacitor (1000µF) near VM |

Speed control is achieved by applying a Pulse Width Modulation (PWM) signal to the driving pin while keeping the other pin LOW. This unique "direct drive" architecture is a key advantage over drivers requiring a separate enable pin, as it allows for more advanced control techniques with fewer I/O pins.

The SOP-8 package takes up a fraction of the space required by an L298N module, making it perfect for micro-robotics (e.g., mini sumo bots, maze solvers).
