Handler Implementation Notes

Series Extraction

// Extract series prefix (MBI + first digit)
// MBI5024GP -> MBI5
// MBI6651 -> MBI6
// MBI1801 -> MBI1

if (upperMpn.matches("^MBI5[0-9]{3}.*")) return "MBI5";
if (upperMpn.matches("^MBI6[0-9]{3}.*")) return "MBI6";
if (upperMpn.matches("^MBI1[0-9]{3}.*")) return "MBI1";

Package Code Extraction

// Pattern: MBI[156]xxx[package-code]
Pattern packagePattern = Pattern.compile("^MBI[156][0-9]{3}([A-Z]{1,2}).*$");

// Decode package using lookup table
PACKAGE_CODES.put("GP", "SOP-24");
PACKAGE_CODES.put("GF", "SSOP-24");
PACKAGE_CODES.put("GN", "QFN");

Base Part Extraction

// Extract MBI[156]xxx - the core 7-character part number
// MBI5024GP -> MBI5024
// MBI5153-TR -> MBI5153

Pattern basePattern = Pattern.compile("^(MBI[156][0-9]{3}).*$");

Matching Patterns

// MBI5xxx - Constant current LED drivers
"^MBI5[0-9]{3}[A-Z0-9-]*$"

// MBI6xxx - DC-DC LED drivers
"^MBI6[0-9]{3}[A-Z0-9-]*$"

// MBI1xxx - Scan drivers
"^MBI1[0-9]{3}[A-Z0-9-]*$"

Helper Methods

The handler provides useful helper methods:

// Get channel count for known parts
int channels = handler.getChannelCount("MBI5024");  // Returns 16

// Check driver type
handler.isConstantCurrentDriver("MBI5024");  // true
handler.isDCDCDriver("MBI6651");             // true
handler.isScanDriver("MBI1801");             // true

// Get series description
handler.getSeriesDescription("MBI5");  // "Constant Current LED Drivers"

Replacement Rules

Same Base Part, Different Package

Parts with the same base number but different packages are replacements:

• MBI5024GP = MBI5024GF = MBI5024GN (same part, different package)
• MBI5024 = MBI5024-TR (same part with/without tape and reel)

Same Series, Different Model

Parts in the same series with different model numbers are NOT replacements:

• MBI5024 (16-ch) != MBI5153 (48-ch) - different channel count
• MBI5024 != MBI5039 - different features (error detection)

LED Display Architecture

Typical LED display driver setup:

MBI5xxx (Column Drivers) - Constant current sink
    |
    v
LED Matrix
    ^
    |
MBI1xxx (Row/Scan Drivers) - P-channel switch

• MBI5xxx: Sinks current through LEDs, controls brightness via PWM
• MBI1xxx: Selects which row of LEDs is active (scan multiplexing)

---

Applications

• LED video walls
• LED signage displays
• Indoor/outdoor LED screens
• LED matrix displays
• Full-color LED panels
• RGB LED modules
• LED backlighting

Learnings & Edge Cases

• MBI prefix: All Macroblock parts start with MBI.
• Series digit significance: 5=constant current sink, 6=DC-DC driver, 1=scan driver.
• Channel count varies: 16-channel parts (MBI50xx) vs 48-channel (MBI51xx/52xx/53xx).
• Package suffix position: 1-2 letters immediately after the 4-digit model number.
• No manufacturer-specific ComponentTypes: Handler uses generic IC and LED_DRIVER types.
• -TR suffix: Tape and Reel is packaging option, not a different part.
• Column vs Row drivers: MBI5xxx drives columns (current sink), MBI1xxx drives rows (switch).
• Error detection feature: MBI5039 has built-in LED open/short detection.
