A5973D Frequently Asked Questions (FAQs)

  • The maximum current rating for the A5973D is 3A per channel, but it's recommended to limit it to 2A for reliable operation.
  • Ensure good airflow, use a heat sink if possible, and keep the device away from other heat sources. The maximum junction temperature is 150°C.
  • The minimum input voltage required is 5.5V, but it's recommended to use a minimum of 6V for reliable operation.
  • Yes, the A5973D is rated for operation up to 150°C, but ensure proper thermal management and consider derating the current output at higher temperatures.
  • Use a voltage regulator or a transient voltage suppressor (TVS) to protect the device from overvoltage conditions. For undervoltage protection, use a voltage supervisor or a reset IC.
