Table
| Check | Result |
|---|---|
| Pin count | Match: symbol/footprint have 20 pads/pins |
| Package family | Match: footprint is clearly a 20-ball WLCSP/BGA-style land pattern |
| Body size naming | Match: footprint asset name encodes roughly 1.58 mm x 1.98 mm |
| Pitch | Match: footprint uses 0.4 mm grid, matching datasheet |
| Pin numbering | Match: A1-A4, B1-B4, C1-C4, D1-D4, E1-E4 all present |
| Functional pad mapping | Match: IN1, IN2, OUT, PR, OV1, OV2, SEL, ST, ILIM, SS, GND all align with datasheet assignment |
| 3D model presence | Present, good for mechanical validation |
Table
| Severity | Finding | Why it matters |
|---|---|---|
| Medium | The part property labeled as datasheet points to the Renesas product page, not the direct PDF | Can slow part review, automation, and downstream verification because the canonical datasheet document is indirect |
| Medium | All symbol terminals are typed as Unspecified instead of Input / Output / Power / Ground | This weakens ERC quality and can hide connection mistakes in future designs using this part |
| Low | The schematic part project currently has no nets defined | Not a footprint error, but it means there is no electrical self-check inside the part project beyond pin presence/mapping |
| Low | The symbol exposes duplicated power balls as separate named terminals rather than merged functional pins | Electrically valid for a part project, but users must understand that multiple balls belong to the same net class in the final design |
Table
| Area | Assessment |
|---|---|
| Wrong pin count risk | No obvious issue found |
| Wrong package risk | No obvious issue found |
| Wrong pin mapping risk | No obvious issue found |
| Footprint pitch/body mismatch risk | No obvious issue found |
| Symbol ERC quality risk | Yes, moderate due to unspecified pin types |
| Datasheet traceability risk | Yes, moderate because the saved datasheet link is not the direct PDF |
