Use when refactoring, cleaning up, or enhancing the lib-electronic-components codebase. Provides guidance on architecture patterns, known issues, duplication hotspots, and recommended improvements.
Base skill for working with electronic components in this library. Use when adding new component types, manufacturer handlers, or working with MPN (Manufacturer Part Number) operations, BOM entries, or component classification.
Use this skill BEFORE creating a PR to ensure all documentation, skills, and learnings are updated. Critical for preserving institutional knowledge and preventing documentation drift.
Use when working with component similarity calculations - comparing MPNs, finding equivalent parts, implementing new similarity calculators, or understanding how component matching works.
Use when working with capacitor similarity calculations - comparing ceramic/electrolytic/film capacitor MPNs, understanding value/voltage/dielectric matching, or capacitor-specific similarity logic.
Use when working with connector similarity calculations - comparing connector MPNs, understanding pin count/pitch/family matching, or connector-specific similarity logic.

Chipone MPNs follow this general structure:
[PREFIX][SERIES][VARIANT][PACKAGE]
| | | |
| | | +-- Package suffix (SS=SSOP, S=SOP, Q=QFN)
| | +-- Variant letter (B, C for improved versions)
| +-- Series number (2024, 2053, 2110, etc.)
+-- Prefix: ICN or ICND (improved series)
ICN2053SS
| | ||
| | |+-- SS = SSOP package
| | +-- (no variant letter)
| +-- 2053 = 16-channel LED driver with S-PWM
+-- ICN = Constant current LED driver prefix
ICND2110-S
| | ||
| | |+-- S = SOP package
| | +-- (hyphen separator)
| +-- 2110 = 16-channel improved LED driver
+-- ICND = Improved series prefix
| Part Number | Channels | Features |
|---|---|---|
| ICN2012 | 12 | Basic LED driver |
| ICN2018 | 18 | Basic LED driver |
| ICN2024 | 24 | 24-channel constant current |
| ICN2026 | 26 | 26-channel constant current |
| ICN2038 | 38 | 38-channel constant current |
| ICN2053 | 16 | S-PWM for high grayscale |
| ICN2065 | 16 | High refresh rate support |
| Part Number | Channels | Features |
|---|---|---|
| ICND2025 | 24 | Improved ICN2024 replacement |
| ICND2053 | 16 | Improved ICN2053 replacement |
| ICND2110 | 16 | Enhanced 16-channel driver |
| Code | Package | Notes |
|---|---|---|
| SS | SSOP | Small outline shrink package |
| S | SOP | Small outline package |
| SOP | SOP | Explicit SOP |
| SSOP | SSOP | Explicit SSOP |
| Q | QFN | Quad flat no-lead |
| QFN | QFN | Explicit QFN |
| T | TSSOP | Thin shrink small outline |
| TSSOP | TSSOP | Explicit TSSOP |
Package codes appear in two ways:
| Letter | Meaning |
|---|---|
| B | Second revision |
| C | Third revision |
| (none) | Original revision |
Single letters like B, C after the part number typically indicate variant revisions, NOT packages.
Example: ICN2065B = ICN2065 revision B
The ICND2xxx series are drop-in replacements for the corresponding ICN2xxx parts:
| Original | Replacement | Notes |
|---|---|---|
| ICN2053 | ICND2053 | Pin-compatible, improved performance |
| ICN2024 | ICND2025 | Similar functionality |
Parts with the same base number in ICN vs ICND series are typically compatible.
// ICN2xxx patterns
"^ICN2[0-9]{3}[A-Z0-9-]*$"
// ICND2xxx patterns (improved series)
"^ICND2[0-9]{3}[A-Z0-9-]*$"
// Step 1: Check for hyphenated suffix first
// ICND2110-S -> S -> SOP
// Step 2: Check for inline suffix
// ICN2053SS -> SS -> SSOP
// Step 3: Skip single variant letters
// ICN2065B -> B is variant, not package -> return ""
// ICND2xxx -> "ICND2"
// ICN2xxx -> "ICN2"
manufacturers/ChiponeHandler.javaIC, LED_DRIVERChipone drivers are commonly used in LED display panels and signage:
When matching BOMs, consider these equivalents:
ICN2053 == ICND2053 (drop-in replacement)
ICN2053SS == ICN2053-SSOP (same package, different notation)
