MPN Structure

Chipone MPNs follow this general structure:

code

[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

code

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

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

ICND2xxx Series - Improved LED Drivers

Part Number	Channels	Features
ICND2025	24	Improved ICN2024 replacement
ICND2053	16	Improved ICN2053 replacement
ICND2110	16	Enhanced 16-channel driver

Package Codes

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 Suffix Positioning

Package codes appear in two ways:

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

Variant Letters

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

Official Replacements

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.

Handler Implementation Notes

Pattern Matching

java

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

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

Package Code Extraction

java

// 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

java

// 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:

code

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.
