Instructions for Using the L6203

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the range of 8V to 35V.
   • Use a stable power supply to avoid voltage fluctuations that can affect performance.

2. Current Limiting:

   • The maximum output current per channel is 2.5A at 25掳C. For higher temperatures, derate the current to ensure reliable operation.
   • Use external current-limiting resistors if necessary to protect the device from overcurrent conditions.

3. Thermal Management:

   • The device has thermal shutdown protection that activates at 150掳C. Ensure adequate heat dissipation by using a heatsink or providing sufficient airflow.
   • Monitor the operating temperature to stay within the range of -40掳C to 125掳C.

4. Input Logic Levels:

   • For the input to be recognized as high, the voltage must be between 2.0V and Vcc.
   • For the input to be recognized as low, the voltage must be between 0V and 1.5V.

5. Output Configuration:

   • The output saturation voltage (Vsat) is typically 1.7V when the output current is 2A and the supply voltage is 24V. This should be considered when designing the load circuit.
   • The device has built-in short-circuit protection to prevent damage in case of a short circuit.

6. Storage:

   • Store the device in a dry environment with temperatures ranging from -40掳C to 150掳C to prevent damage.

7. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal components.
   • Follow proper soldering techniques to ensure good electrical connections and to prevent thermal stress.

By following these guidelines, you can ensure the reliable operation and longevity of the L6203.
