E-TDA7385 Frequently Asked Questions (FAQs)

  • A good PCB layout for the E-TDA7385 involves keeping the power supply lines (VIN and VOUT) as short as possible, using a star connection for the ground pins, and placing the input and output capacitors close to the IC. A 4-layer PCB with a solid ground plane is recommended.
  • Choose X7R or X5R ceramic capacitors with a voltage rating of at least 1.5 times the input voltage. The capacitance value depends on the application, but a good starting point is 10uF for the input capacitor and 22uF for the output capacitor.
  • The maximum ambient temperature for the E-TDA7385 is 85°C, but it can be derated to 70°C for high-reliability applications. Ensure good heat dissipation and consider using a heat sink if the device will be operating at high temperatures.
  • Use a voltage supervisor or a reset IC to monitor the input voltage and reset the E-TDA7385 if it falls outside the recommended range (7V to 18V). You can also add a voltage clamp or a TVS diode to protect against overvoltage transients.
  • Yes, but take precautions to minimize electromagnetic interference (EMI). Use a shielded enclosure, keep the PCB layout compact, and add EMI filters or ferrite beads to the input and output lines if necessary.
