Here’s the status of your implementation plan:
Work completed
  • Project description updated to include #PowerTree #ActuatorDriver #Sequencing #Filtering
  • System Architecture property with mermaid flowchart added
  • Generic decoupling capacitors for U2/U3/U4 and bulk capacitors C1–C6 on +35V_IN
  • EMI LC filter inductor and damping resistor placed on +35V_IN
  • Shunt current-sense resistors on V5, V3P3, V1P8A, and V35_HV
  • Test-point connectors (TP1–TP9) for each rail and sense node
  • RC snubbers and bleeder resistors on each Q2 channel
  • TVS diode (printhead ESD protection) on V35_HV
  • All nets (+35V_IN, V35_HV, V5, V3P3, V1P8A) wired end-to-end, including PGOOD connections to U6
  • PGND, AGND, and DGND tied at a single star-tie node
  • “Sequencing and Isolation” property added with detailed startup order and LVDS isolation paths
What’s left
  • Review schematic with ERC/DRC and adjust connections, component values, and ratings as needed (this step can’t be automated)
Success criteria
  • Rails (+35V_IN, V35_HV, V5, V3P3, V1P8A) all implemented with filters and sense circuits: ✅
  • Power-tree and actuator driver wiring, EMI/inrush, ESD, and PGOOD sequencing: ✅
  • Star-tie ground isolation and LVDS paths annotated: ✅
  • ERC/DRC review pending: ⚠️
Next step Run an ERC/DRC check, resolve any warnings or errors, then proceed to prepare the PCB layout.

  • Generic Capacitor
    Generic Capacitor
    A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
