TLV1391CDBVR datasheet by Texas Instruments

TLV1391CDBVR Frequently Asked Questions (FAQs)

• What is the recommended layout and routing for the TLV1391CDBVR to minimize noise and ensure optimal performance?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital grounds separate. Additionally, it's recommended to use a star-configuration for the power supply and to keep the input and output traces short and away from each other.
• How do I handle the power-on reset (POR) and brown-out reset (BOR) in my design?
  The TLV1391CDBVR has a built-in POR and BOR circuitry. To handle these, ensure that the power supply is stable and within the recommended operating range. Also, add a capacitor between the VCC and GND pins to filter out noise and ensure a clean power-on reset.
• What is the recommended input and output capacitance for the TLV1391CDBVR?
  The recommended input capacitance is 10nF to 100nF, and the recommended output capacitance is 10nF to 1uF. However, the optimal capacitance values may vary depending on the specific application and operating frequency.
• How do I ensure electromagnetic compatibility (EMC) and reduce electromagnetic interference (EMI) in my design?
  To ensure EMC and reduce EMI, use a shielded enclosure, keep the analog and digital circuits separate, and use a common-mode choke or ferrite bead on the input and output lines. Additionally, ensure that the PCB layout is optimized for minimal radiation and that the device is properly grounded.
• What is the recommended operating temperature range for the TLV1391CDBVR?
  The recommended operating temperature range for the TLV1391CDBVR is -40°C to 125°C. However, the device can operate up to 150°C for short periods of time. Ensure that the device is properly heat-sinked and that the operating temperature is within the recommended range for optimal performance and reliability.
