R6004ENX - ROHM Semiconductor

R6004ENX Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal thermal performance?
  ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
• How do I ensure stable operation with a high-impedance output load?
  To ensure stable operation with a high-impedance output load, add a 10nF to 100nF capacitor in parallel with the output resistor to reduce oscillation. Additionally, consider adding a 1kΩ to 10kΩ resistor in series with the output to improve stability.
• What is the maximum allowed voltage on the EN pin?
  The maximum allowed voltage on the EN (enable) pin is 6V. Exceeding this voltage may cause damage to the internal circuitry. It's recommended to use a voltage limiter or a resistor divider to ensure the EN pin voltage remains within the specified range.
• Can I use the R6004ENX in a high-temperature environment?
  The R6004ENX is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's essential to consider the thermal design and ensure proper heat dissipation to maintain reliable operation.
• How do I handle the power-on reset (POR) and brown-out detection (BOD) features?
  The R6004ENX has an internal POR and BOD circuitry. To handle these features, ensure that the input voltage rises monotonically during power-up, and the voltage supervisor circuit is properly configured to detect brown-out conditions. Consult the datasheet and application notes for specific guidelines.
