UCC3808AD-1G4 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with short traces, and placing the IC close to the power stage. Additionally, a solid ground plane and a separate analog ground plane can help reduce noise and EMI. Refer to the application note SLUA271 for more details.
  • The choice of external components depends on the specific application requirements. For the voltage reference, a 2.5V or 3.3V reference is recommended. For the current sense resistors, the value depends on the maximum current and the desired accuracy. Refer to the datasheet and application notes for more information.
  • The UCC3808AD-1G4 has an operating temperature range of -40°C to 125°C. However, the device can be operated up to 150°C with derating. Refer to the datasheet for more information on thermal derating.
  • The UCC3808AD-1G4 has a built-in overcurrent protection feature. The OCP pin can be connected to a resistor and capacitor to set the overcurrent threshold and response time. Refer to the datasheet and application notes for more information on implementing overcurrent protection.
  • The recommended input voltage range for the UCC3808AD-1G4 is 8.5V to 14V. However, the device can operate up to 16V with reduced performance. Refer to the datasheet for more information on input voltage range and performance.
