TRS3221EIRGTR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. Also, it's recommended to use a 10uF capacitor between VCC and GND, and to keep the input and output traces as short as possible.
  • The thermal shutdown feature is activated when the junction temperature exceeds 150°C. To handle this, ensure good thermal design and heat dissipation, and consider using a heat sink if necessary. Also, monitor the device temperature and take corrective action if thermal shutdown occurs.
  • The recommended input capacitance is 10uF, and the recommended output capacitance is 10uF to 22uF. However, the optimal capacitance values may vary depending on the specific application and operating conditions.
  • To ensure EMC, use a shielded enclosure, keep the PCB layout compact, and use a common-mode choke or ferrite bead on the input and output lines. Also, ensure that the device is properly decoupled and that the power supply is well-regulated.
  • The recommended start-up sequence is to apply power to the VCC pin first, followed by the input signal. This ensures that the device is properly biased and configured before the input signal is applied.
