Component Type Mapping

The MPSHandler supports these ComponentTypes:

| MPN Pattern | ComponentType | Description | |-------------|---------------|-------------| | MP1xxx, MP2xxx, MP4xxx, MP5xxx, MP7xxx, MP8xxx, MP9xxx | VOLTAGE_REGULATOR | DC-DC converters and regulators | | MPQxxxx (except 3xxx/6xxx) | VOLTAGE_REGULATOR | Automotive DC-DC converters | | MPMxxxx | VOLTAGE_REGULATOR | Power modules | | MP3xxx | LED_DRIVER | LED driver ICs | | MPQ3xxx | LED_DRIVER | Automotive LED drivers | | MP6xxx | MOTOR_DRIVER | Motor controller ICs | | MPQ6xxx | MOTOR_DRIVER | Automotive motor drivers | | All MPS parts | IC | Base IC type for all parts |

Series Extraction Rules

The handler extracts series as follows:

// MPM series: returns "MPM"
"MPM3610GQV-Z" -> "MPM"

// MPQ series: returns "MPQ"
"MPQ4560GQ-AEC1-LF-Z" -> "MPQ"

// Standard MP[1-9]xxx: returns first 3 characters
"MP1584EN-LF-Z" -> "MP1"
"MP2307DN-LF-Z" -> "MP2"
"MP6500HF" -> "MP6"

Series Descriptions

| Series | Category | |--------|----------| | MP1 | Step-Down Converters | | MP2 | Step-Down/LDO Converters | | MP3 | LED Drivers | | MP4 | High-Current Step-Down | | MP5 | Step-Up/SEPIC Converters | | MP6 | Motor Drivers | | MP7 | Power Switches | | MP8 | Multi-Channel PMIC | | MP9 | High-Voltage Converters | | MPQ | Automotive Grade | | MPM | Power Modules |

Package Code Extraction Rules

The handler extracts package codes with this logic:

  1. Remove common suffixes: -LF-Z, -Z, -LF, -AEC1, etc.
  2. Match pattern: MP[A-Z]?[0-9]{3,4}([A-Z]{2}).*
  3. Look up the 2-letter code in the PACKAGE_CODES map
  4. Return the mapped package name or the raw code
// Example extraction:
"MP1584EN-LF-Z"
  -> Remove suffix: "MP1584EN"
  -> Match: group(1) = "EN"
  -> Lookup: PACKAGE_CODES.get("EN") = "SOIC-8E"

"MPQ4560GQ-AEC1-LF-Z"
  -> Remove suffix: "MPQ4560GQ"
  -> Match: group(1) = "GQ"
  -> Lookup: PACKAGE_CODES.get("GQ") = "QFN"

Official Replacement Logic

The handler identifies official replacements in two scenarios:

Same Base Part, Different Package

MP1584EN <-> MP1584DN   // Same part, different package (SOIC-8E vs SO-8)

Automotive Equivalents (MPQ vs MP)

MP4560GQ <-> MPQ4560GQ  // Consumer vs automotive grade

The isOfficialReplacement() method checks:

  1. Automotive equivalents (MPQ ↔ MP with same 4-digit number)
  2. Same series and same base part number

Automotive Detection

MPS uses two indicators for automotive-grade parts:

// Method: isAutomotiveGrade(String mpn)

// 1. MPQ prefix indicates automotive
"MPQ4560GQ-LF-Z" -> true

// 2. -AEC suffix indicates automotive qualification
"MP4560GQ-AEC1-LF-Z" -> true

// Standard consumer parts
"MP4560GQ-LF-Z" -> false

Handler Implementation Notes

Supported Types Declaration

The handler uses Set.of() for immutable type set:

public Set<ComponentType> getSupportedTypes() {
    return Set.of(
            ComponentType.IC,
            ComponentType.VOLTAGE_REGULATOR,
            ComponentType.LED_DRIVER,
            ComponentType.MOTOR_DRIVER
    );
}

Pattern Registration

Patterns are registered for both specific and base types:

// MP3xxx registered for both LED_DRIVER and IC
registry.addPattern(ComponentType.LED_DRIVER, "^MP3[0-9]{3}[A-Z0-9-]*$");
registry.addPattern(ComponentType.IC, "^MP3[0-9]{3}[A-Z0-9-]*$");

matches() Implementation

The handler overrides matches() for efficient direct pattern checking:

// Direct pattern checks by type for performance
switch (type) {
    case VOLTAGE_REGULATOR:
        return isVoltageRegulator(upperMpn);
    case LED_DRIVER:
        return isLEDDriver(upperMpn);
    case MOTOR_DRIVER:
        return isMotorDriver(upperMpn);
    case IC:
        return isMPSPart(upperMpn);
}

Learnings & Edge Cases

  • MPQ vs MP: The automotive variant MPQ has a 4-digit part number (MPQ4560) while standard MP uses 4 digits after the prefix character (MP4560). This is a 1-character offset when extracting the numeric part.
  • AEC suffix: Parts can be automotive without MPQ prefix if they have -AEC1 suffix. Always check both.
  • Package code position: Package codes come immediately after the part number digits, before any hyphens. The handler strips -LF-Z and similar suffixes before extraction.
  • Module prefix MPM: Power modules have their own prefix and are different from standard MP parts - they include an integrated inductor.
  • Series overlap: MP6xxx (motor drivers) and MPQ6xxx are the same - both are motor drivers. Same for MP3xxx/MPQ3xxx (LED drivers). The MPQ prefix only adds automotive qualification.
  • getSupportedTypes() uses Set.of(): The handler correctly uses immutable Set.of() instead of HashSet.
  • No manufacturer-specific types: Unlike some handlers, MPS doesn't define manufacturer-specific ComponentTypes like VOLTAGE_REGULATOR_MPS. It uses the base types directly.
