TMS44400-60DJ datasheet by Texas Instruments

TMS44400-60DJ Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane and thermal vias to dissipate heat. A minimum of 2 oz copper thickness is recommended for the top and bottom layers.
• How do I ensure reliable operation at high temperatures?
  Ensure proper heat sinking, use a thermal interface material (TIM) between the device and heat sink, and follow the recommended operating conditions and thermal design guidelines.
• What is the maximum allowed voltage on the input pins?
  The maximum allowed voltage on the input pins is 5.5V, which is the absolute maximum rating. However, it's recommended to keep the input voltage within the recommended operating range of 3.3V ± 10% to ensure reliable operation.
• Can I use the TMS44400-60DJ in a 5V system?
  While the device can tolerate 5V on the input pins, it's not recommended to operate the device at 5V continuously. The recommended operating voltage is 3.3V ± 10%. If you need to interface with a 5V system, use a level translator or voltage regulator to ensure compatibility.
• How do I handle ESD protection for the TMS44400-60DJ?
  Texas Instruments recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input and output pins to protect against electrostatic discharge. Follow the recommended ESD protection circuitry and handling procedures to prevent damage.
