TDA2005S Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the TDA2005S?
  The recommended operating voltage range for the TDA2005S is 12V to 18V, with a typical voltage of 15V.
• How do I ensure the TDA2005S operates within its safe operating area (SOA)?
  To ensure the TDA2005S operates within its SOA, ensure that the output current does not exceed 2.5A, and the junction temperature does not exceed 150°C. Also, ensure that the device is properly heatsinked and the thermal resistance (RthJA) is minimized.
• What is the purpose of the bootstrap capacitor (Cb) in the TDA2005S?
  The bootstrap capacitor (Cb) is used to generate the high-side gate drive voltage for the internal power MOSFET. It is recommended to use a capacitor with a value between 10nF to 100nF.
• How do I choose the correct value for the input capacitor (Ci) in the TDA2005S?
  The input capacitor (Ci) should be chosen based on the input voltage ripple and the desired output voltage ripple. A general rule of thumb is to choose a capacitor with a value between 10uF to 100uF, with a voltage rating of at least 25V.
• What is the purpose of the internal overcurrent protection (OCP) in the TDA2005S?
  The internal overcurrent protection (OCP) in the TDA2005S is designed to protect the device from excessive current conditions. If the output current exceeds 2.5A, the OCP will limit the current to prevent damage to the device.
