The workhorses of LED display drivers. | Part | Channels | Features | |------|----------|----------| | MBI5024 | 16 | Basic constant current | | MBI5039 | 16 | Error detection | | MBI5040 | 16 | Enhanced features | | MBI5041 | 16 | Variant | | MBI5042 | 16 | Variant | | MBI5050 | 16 | High-end 16-ch | | MBI5124 | 16 | Enhanced variant | | MBI5153 | 48 | High channel count | | MBI5252 | 48 | Enhanced 48-ch | | MBI5353 | 48 | Premium 48-ch | ### MBI6xxx Series - DC-DC LED Drivers Switching LED drivers for backlighting and general LED lighting. | Part | Description | |------|-------------| | MBI6651 | DC-DC LED driver | | MBI6652 | Enhanced variant | | MBI6661 | High power variant | ### MBI1xxx Series - Scan Drivers Row/scan drivers for LED matrix displays, work in conjunction with MBI5xxx column drivers. | Part | Description | |------|-------------| | MBI1801 | P-channel scan driver | | MBI1802 | Enhanced scan driver | --- ## Package Codes | Code | Package | Notes | |------|---------|-------| | GP | SOP-24 | Standard SOP package | | GF | SSOP-24 | Shrink SOP | | GH | TSSOP-24 | Thin SOP | | GS | SSOP-24 | SSOP variant | | GT | TSSOP-24 | TSSOP variant | | GN | QFN | Quad flat no-lead | | GQ | QFN | QFN variant | | TE | TQFP | Thin QFP | | TF | TQFP-48 | 48-pin TQFP | | TP | TQFP-64 | 64-pin TQFP | | S | SOP | SOP generic | | T | TSSOP | TSSOP generic | | N | QFN | QFN generic | | P | PDIP | Through-hole DIP | ### Options | Suffix | Meaning | |--------|---------| | -TR | Tape and Reel packaging | --- ## Channel Count Reference | Part | Channels | Application | |------|----------|-------------| | MBI5024 | 16 | Standard displays | | MBI5039 | 16 | With fault detection | | MBI5050 | 16 | Premium 16-ch | | MBI5153 | 48 | High-density displays | | MBI5252 | 48 | Enhanced 48-ch | | MBI5353 | 48 | Premium 48-ch | --- ## Handler Implementation Notes ### Series Extraction ```java // 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 ```java // Pattern: MBI[156]xxx[package-code] Pattern packagePattern = Pattern.compile("^MBI[156][0-9]{3}([A-Z]{1,2}).*$"); // Decode package using lookup table PACKAGE_CODES.put("GP", "SOP-24"); PACKAGE_CODES.put("GF", "SSOP-24"); PACKAGE_CODES.put("GN", "QFN"); ``` ### Base Part Extraction ```java // Extract MBI[156]xxx - the core 7-character part number // MBI5024GP -> MBI5024 // MBI5153-TR -> MBI5153 Pattern basePattern = Pattern.compile("^(MBI[156][0-9]{3}).*$"); ``` ### Matching Patterns ```java // 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: ```java // 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) --- ## Related Files - Handler: `manufacturers/MacroblockHandler.java` - Component types: `ComponentType.IC`, `ComponentType.LED_DRIVER` --- ## Common MPNs | MPN | Description | Channels | |-----|-------------|----------| | MBI5024GP | Constant current, SOP-24 | 16 | | MBI5039GP | With error detection, SOP-24 | 16 | | MBI5153 | High channel count | 48 | | MBI5252 | Enhanced 48-ch | 48 | | MBI6651 | DC-DC driver | N/A | | MBI1801 | Scan driver | N/A | --- ## 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. <!-- Add new learnings above this line -->
