MPN Structure

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)

Example Decoding

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

Product Families

ICN2xxx Series - Constant Current LED Drivers

ICND2xxx Series - Improved LED Drivers

Package Codes

Package Suffix Positioning

Package codes appear in two ways:

1. Inline: Directly after the part number (ICN2053SS)
2. Hyphenated: After a hyphen (ICND2110-S)

Variant Letters

Single letters like B, C after the part number typically indicate variant revisions, NOT packages.

Example: ICN2065B = ICN2065 revision B

Official Replacements

The ICND2xxx series are drop-in replacements for the corresponding ICN2xxx parts:

Parts with the same base number in ICN vs ICND series are typically compatible.

Handler Implementation Notes

Pattern Matching

// ICN2xxx patterns
"^ICN2[0-9]{3}[A-Z0-9-]*$"

// ICND2xxx patterns (improved series)
"^ICND2[0-9]{3}[A-Z0-9-]*$"

Package Code Extraction

// 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 ""

Series Extraction

// ICND2xxx -> "ICND2"
// ICN2xxx -> "ICN2"

Common Use Cases

LED Display Panels

Chipone drivers are commonly used in LED display panels and signage:

• Indoor LED screens: ICN2053, ICND2053 (high grayscale)
• Outdoor LED screens: ICN2024, ICN2038 (high channel count)
• High refresh displays: ICN2065 (high refresh rate)

BOM Matching

When matching BOMs, consider these equivalents:

ICN2053 == ICND2053 (drop-in replacement)
ICN2053SS == ICN2053-SSOP (same package, different notation)

Learnings & Edge Cases

• Variant vs Package: Single letters after the part number (B, C) are variants, not packages. Multi-letter suffixes (SS, QFN) are packages.
• ICND prefix: The "D" in ICND stands for an improved/digital version, not a package code.
• Channel count from part number: The last 2-3 digits sometimes indicate channel count (2024 = 24ch, 2012 = 12ch), but this is not universal.
• Tape and reel: -TR suffix indicates tape and reel packaging, should be stripped before package extraction.
