UCC2817ADR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a compact layout with the UCC2817ADR placed close to the power MOSFETs, with short traces and minimal inductance. A 4-layer PCB with a solid ground plane is recommended. See the TI application note SLUA443 for more details.
  • Choose resistors with low tolerance (e.g., 1%) and temperature coefficient (e.g., 50 ppm/°C) to ensure accurate voltage and current sensing. The values of the resistors depend on the specific application and the desired voltage and current sensing ranges.
  • The maximum voltage that can be applied to the VCC pin is 18V, but it's recommended to keep it below 15V for reliable operation. Exceeding 18V can cause damage to the device.
  • The OCP threshold is set by the RSENSE resistor. Choose a suitable value for RSENSE based on the desired OCP threshold and the sense resistor value. Ensure that the sense resistor is placed close to the power MOSFET and that the layout is designed to minimize noise and interference.
  • Yes, but the UCC2817ADR is optimized for use with N-channel power MOSFETs. If using a different type of power MOSFET, ensure that the gate drive voltage and current requirements are compatible with the UCC2817ADR's output stage.
