Part Review Audit

flux

I’ll inspect the part metadata, look for an official datasheet if needed, update the Datasheet property, then verify symbol/footprint/pin data against the source and summarize any mismatches.

Review complete. The pinout and HTSSOP-B20 footprint match the ROHM datasheet; key issues flagged are the incorrect Part Type (Electromechanical Components), non-canonical stored datasheet URL versus the official ROHM URL, all pins having Unspecified pin type, and a truncated description.
I created the full report here: Part Information Review: BV2HM050EFV-CE2.
Suggested next steps:
  • Update Part Type to an IC / power-management / high-side-switch category.
  • Replace or supplement the Datasheet URL with the official ROHM PDF.
  • Add proper pin types and descriptions, especially ST1/ST2 as open-drain diagnostics and pad 21 as EXP-PAD / VBB.

Functional notes from the datasheet:
  • Built-in hiccup-mode overcurrent protection, thermal shutdown, open-load detection, and UVLO.
  • IN1/IN2 include internal pull-down resistors.
  • ST1/ST2 are open-drain diagnostic outputs and require pull-up resistors to the MCU supply in the application example.

Pinout conclusion: no substantive pin-number/name mismatch was found.
Footprint Cross-Check
Observed footprint: SOP65P640X100-21N, with KiCad module description HTSSOP-B20.
Observed footprint geometry from the asset:
  • 20 perimeter SMD pads plus exposed pad 21.
  • Lead pitch: 0.65 mm.
  • Perimeter pad size: 0.45 mm × 1.475 mm.
  • Pin rows centered at x = ±2.938 mm, giving row-center span about 5.876 mm.
  • Exposed pad: 2.4 mm × 4.0 mm.
  • Fab outline: 4.4 mm × 6.5 mm.
  • Courtyard: 7.85 mm × 7.10 mm.
  • Pin-1 chamfer/marking present on fab/silk.
Datasheet/package data extracted:
  • Package: HTSSOP-B20.
  • Package W typ × D typ × H max: 6.5 mm × 6.4 mm × 1.0 mm.
  • Mold/body width from mechanical extraction: 4.4 ± 0.1 mm.
  • Lead pitch: 0.65 mm.
  • Exposed pad / thermal pad: 2.4 mm × 4.0 mm.
Footprint conclusion: footprint name, pin count, pitch, exposed pad size, and HTSSOP-B20 mapping are consistent with the datasheet extraction. The 4.4 mm fab width vs 6.4 mm package width appears to be body width vs overall lead-span/package width, not a mismatch.
Mismatches / Issues Flagged
  1. Part Type is incorrect
    • Current value: Electromechanical Components.
    • Datasheet/device class: automotive intelligent power device / 2-channel high-side switch IC / power management IC.
    • Recommended correction: use the closest Flux taxonomy value for Integrated Circuit, Power Management, Power Switch IC, or High-Side Switch.
  2. Current Datasheet URL is not the canonical manufacturer URL
    • A Datasheet URL is already set, so no missing-datasheet update was required by the user instruction.
    • However, the current project property points to a storage-hosted uploaded PDF.
    • Recommended canonical URL: https://fscdn.rohm.com/en/products/databook/datasheet/ic/power/ipd/bv2hm050efv-c-e.pdf.
  3. Pin Type fields are all Unspecified
    • This does not change the visual pinout, but it weakens ERC/model quality.
    • Recommended pin types:
      • VBB and EXP-PAD/VBB: Power In / power input.
      • GND: Ground.
      • IN1/IN2: Input.
      • ST1/ST2: Open Collector/Open Drain output if available, otherwise Output.
      • OUT1/OUT2: Power Out / output.
      • N.C.: Not Connected.
  4. Description is truncated
    • The project description appears cut off at “under v”.
    • Recommended description: “ROHM BV2HM050EFV-CE2 automotive IPD Series 2-channel high-side switch in HTSSOP-B20 with hiccup overcurrent protection, thermal shutdown, open-load detection, UVLO, and diagnostic outputs.”
  5. Exposed pad naming could be clearer
    • Modeled as VBB_2 with pin number 21, which is acceptable for EDA.
    • Recommended description/name note: EXP-PAD / VBB to avoid confusion because the datasheet labels it EXP-PAD rather than numeric pin 21.
Items Not Flagged as Mismatches
  • MPN BV2HM050EFV-CE2: matches ordering code.
  • Manufacturer Rohm: acceptable; ROHM Semiconductor would be a cleaner distributor-oriented spelling but not wrong.
  • Pinout: all pins 1-20 and exposed pad agree with the datasheet.
  • Footprint: HTSSOP-B20 / 0.65 mm pitch / 20 leads + exposed pad geometry is consistent with extracted datasheet data.
  1. Update Part Type from Electromechanical Components to the closest IC/power-management/high-side-switch category.
  2. Replace or supplement the current Datasheet URL with the official ROHM URL.
  3. Add explicit pin descriptions and electrical pin types to all terminals.
  4. Update the project/part description to remove truncation and include the protection/diagnostic features.
  5. Rename or describe pad 21 as EXP-PAD / VBB while preserving VBB connectivity.
