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.
