DAN217FHT146 datasheet by ROHM Semiconductor

DAN217FHT146 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.
• How do I ensure the device is properly biased for optimal performance?
  The DAN217FHT146 requires a stable input voltage (Vin) between 4.5V to 36V, and a bias voltage (Vcc) between 4.5V to 15V. Ensure the input voltage is filtered and decoupled to prevent noise and oscillations.
• What is the maximum allowed power dissipation for this device?
  The maximum power dissipation for the DAN217FHT146 is 2.5W. Ensure the device is properly heat-sinked and the PCB is designed to dissipate heat efficiently to prevent overheating.
• Can I use this device in a high-reliability or automotive application?
  Yes, the DAN217FHT146 is AEC-Q100 qualified, making it suitable for automotive and high-reliability applications. However, ensure you follow ROHM's guidelines for qualification and testing.
• How do I protect the device from overvoltage and overcurrent conditions?
  Implement overvoltage protection (OVP) and overcurrent protection (OCP) circuits to prevent damage to the device. ROHM recommends using a voltage regulator with built-in OVP and OCP features.
