Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (Vcc) is within the specified range of 4.5V to 28V.
   • Connect the power supply to the Vcc pin and ground to the GND pin.

2. Channel Configuration:

   • Each channel can handle a continuous current of up to 1.5A and a peak current of up to 3A.
   • Connect the load to the OUT pins corresponding to the desired channels.

3. Control Signals:

   • Control each channel by applying a logic high or low signal to the IN pins.
   • Logic high turns the channel on, allowing current to flow through the load.
   • Logic low turns the channel off, disconnecting the load from the power supply.

4. Protection Features:

   • The device includes overcurrent, overtemperature, and short-circuit protection.
   • In case of a fault, the affected channel will be automatically turned off to prevent damage.

5. Thermal Management:

   • Ensure proper heat dissipation by providing adequate cooling, such as a heatsink or forced air cooling, especially when operating at high currents or in high ambient temperatures.
   • Monitor the temperature to ensure it stays within the operating range of -40°C to 125°C.

6. Storage and Handling:

   • Store the device in a dry environment with temperatures between -65°C and 150°C.
   • Handle with care to avoid mechanical stress or damage to the leads.

7. Mounting:

   • Solder the device to the PCB using standard soldering techniques.
   • Ensure all connections are secure and free from shorts or cold solder joints.

8. Testing:

   • After assembly, test each channel to ensure proper operation.
   • Verify that the control signals correctly turn the channels on and off.
   • Check for any signs of overheating or abnormal behavior during operation.
