TPS2813DR datasheet by Texas Instruments

TPS2813DR Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the TPS2813DR?
  The TPS2813DR can operate from -40°C to 125°C, but the junction temperature should not exceed 150°C.
• How do I ensure the TPS2813DR is properly powered up and initialized?
  The TPS2813DR has an internal power-on reset (POR) circuit that ensures the device is properly powered up and initialized. However, it's recommended to add an external capacitor between the VCC and GND pins to filter out noise and ensure a clean power-up sequence.
• What is the recommended layout and routing for the TPS2813DR to minimize EMI and noise?
  To minimize EMI and noise, it's recommended to follow a star-grounding layout, keep the input and output traces short and away from each other, and use a solid ground plane. Additionally, adding a ferrite bead or a common-mode choke can help filter out high-frequency noise.
• Can I use the TPS2813DR in a high-reliability or automotive application?
  Yes, the TPS2813DR is qualified for automotive and high-reliability applications. It meets the requirements of the AEC-Q100 standard and is designed to withstand harsh operating conditions, including high temperatures, humidity, and vibration.
• How do I troubleshoot issues with the TPS2813DR, such as unexpected shutdowns or incorrect output voltages?
  To troubleshoot issues with the TPS2813DR, start by checking the input voltage, output voltage, and current consumption. Use an oscilloscope to monitor the output voltage and current, and check for any signs of oscillation or instability. Also, verify that the device is properly configured and that the input and output capacitors are correctly sized and placed.
