TA75339F Parameter Table

TA75339F Instructions

1. Supply Voltage:

   • The supply voltage (Vcc) should be between 4.5V and 18V. Ensure that the power supply is stable and within this range to avoid damage to the IC.

2. Quiescent Current:

   • The quiescent current (IQ) is typically around 5mA when there is no load. This value can help in calculating the power consumption of the circuit.

3. Output Current:

   • Each channel can provide up to 2.5A of output current. However, it is recommended to operate at or below 1.5A to ensure reliable operation and prevent overheating.

4. Power Dissipation:

   • The power dissipation per channel is typically 1.5W. Ensure that the heat sink is adequate to dissipate this power, especially when operating at higher currents.

5. Operating Temperature:

   • The IC can operate over a temperature range from -40°C to 85°C. Ensure that the ambient temperature does not exceed these limits to maintain reliable performance.

6. Storage Temperature:

   • The storage temperature range is from -65°C to 150°C. Store the IC in a dry and cool environment to prevent damage.

7. Maximum Junction Temperature:

   • The maximum junction temperature (Tjmax) is 150°C. Monitor the temperature of the IC during operation to ensure it does not exceed this limit.

8. Thermal Resistance:

   • The thermal resistance (θja) is 50°C/W for the TO-220 package. Use a suitable heat sink to reduce the junction temperature, especially under high power conditions.

9. Pin Configuration:

   • Pin 1: IN1 (Input 1)
   • Pin 2: IN2 (Input 2)
   • Pin 3: GND (Ground)
   • Pin 4: OUT1 (Output 1)
   • Pin 5: OUT2 (Output 2)
   • Pin 6: Vcc (Supply Voltage)
   • Pin 7: NC (No Connection)
   • Pin 8: NC (No Connection)

10. Application Notes:

    • Heat Management: Use a heat sink with good thermal conductivity to manage heat dissipation, especially when driving high currents.
    • Input Protection: Consider adding input protection circuits to prevent damage from voltage spikes or reverse polarity.
    • Output Filtering: Use capacitors on the output to filter out any noise and improve stability.

By following these parameters and instructions, you can ensure the reliable operation of the TA75339F in your application.
