// Extract 2-4 uppercase letters optionally followed by digits // Remove G and /TR suffixes first String baseMpn = upperMpn.replaceAll("G?(/TR)?$", ""); // Find package code pattern Pattern packagePattern = Pattern.compile(".*?([XYUQ][A-Z]*[0-9]*)(?:G?(/TR)?)?$"); ``` ### Series Extraction ```java // SGM58xxx is special (5 digits) // Other series are 4 digits: SGM2xxx, SGM4xxx, SGM6xxx, SGM8xxx if (upperMpn.startsWith("SGM58") && upperMpn.length() >= 8) { return "SGM58"; // High-precision ADC series } if (upperMpn.matches("^SGM[0-9][0-9]{3}.*")) { return upperMpn.substring(0, 4); // SGM2, SGM4, SGM6, SGM8 } ``` ### Op-Amp vs Comparator Detection ```java // Op-amps: SGM80xx through SGM85xx private boolean isOpAmp(String mpn) { return mpn.matches("^SGM8[0-5][0-9]{2}[A-Z0-9./-]*$"); } // Comparators: SGM87xx and higher private boolean isComparator(String mpn) { return mpn.matches("^SGM8[7-9][0-9]{2}[A-Z0-9./-]*$"); } ``` ### Voltage in MPN ```java // Voltage can appear as -3.3 or -3.0 in the MPN // SGM2019-3.3YN5G/TR -> 3.3V output // The handler allows dots in MPN patterns: [A-Z0-9./-]* ``` ### Product Type Detection ```java public boolean isLDOPart(String mpn) { return mpn.matches("^SGM2[0-9]{3}[A-Z0-9./-]*$"); } public boolean isDCDCPart(String mpn) { return mpn.matches("^SGM6[0-9]{3}[A-Z0-9./-]*$"); } public boolean isOpAmpPart(String mpn) { return mpn.matches("^SGM8[0-5][0-9]{2}[A-Z0-9./-]*$"); } public boolean isComparatorPart(String mpn) { return mpn.matches("^SGM8[7-9][0-9]{2}[A-Z0-9./-]*$"); } ``` --- ## Related Files - Handler: `manufacturers/SGMicroHandler.java` - Component types: `IC`, `VOLTAGE_REGULATOR`, `OPAMP` - Test file: `handlers/SGMicroHandlerTest.java` --- ## Learnings & Edge Cases - **Voltage in MPN**: LDO parts often include output voltage in the MPN (e.g., SGM2019-3.3) - **Dot character in MPN**: Pattern must allow dots for voltage codes (3.3V, 1.8V, etc.) - **Package code prefix**: Y = SOT/SOIC, X = SC70/MSOP, U = WLCSP - **G suffix**: Indicates RoHS/Green compliance, not part of package code - **Op-amp numbering**: SGM8051 = single, SGM8262 = dual (similar to industry standard) - **SGM8xxx split**: 80-85xx are op-amps, 87-89xx are comparators - **ADC series**: SGM58xxx has 5 digits (unlike other 4-digit series) - **Trailing /TR**: Common tape and reel suffix, strip before package extraction - **No slash in patterns**: Despite /TR suffix, base patterns use [A-Z0-9./-] to handle it <!-- Add new learnings above this line -->
