# 3PEAK Manufacturer Skill ## MPN Structure 3PEAK MPNs follow this general structure: ``` TP[SERIES][VARIANT]-[PACKAGE][OPTIONS] │ │ │ │ │ │ │ │ │ └── Optional: voltage options (-5, -33) │ │ │ └── Package code (TR, QR, MR, DR) │ │ └── Part number within series │ └── Series (1xxx=Op-Amp, 2xxx=Precision, 5xxx=ADC, 7xxx=LDO, 1xx=Current Sense) └── 3PEAK prefix ``` ### Example Decoding ``` TP1541-TR │ │ │ │ │ └── TR = SOT-23 package, Tape & Reel │ └── 1541 = Op-Amp series └── TP = 3PEAK prefix TP7150-MR-33 │ │ │ │ │ │ │ └── -33 = 3.3V output option │ │ └── MR = MSOP package │ └── 7150 = LDO regulator series └── TP = 3PEAK prefix ``` --- ## Package Codes | Code | Package | Notes | |------|---------|-------| | TR | SOT-23 | Small signal | | QR | QFN | Quad Flat No-lead | | MR | MSOP | Mini Small Outline | | DR | SOIC | Small Outline IC | | SR | SOP | Small Outline Package | | PR | TSSOP | Thin Shrink SOP | --- ## Product Series ### Op-Amps (TP1xxx, TP2xxx) | Series | Type | Key Features | |--------|------|--------------| | TP1541 | General Op-Amp | Single supply, rail-to-rail | | TP2111 | Precision Op-Amp | Low offset, high CMRR | | TP2304 | Precision Op-Amp | Low noise | | TP2071 | General Op-Amp | Single supply | | TP2072 | Dual Op-Amp | Rail-to-rail | | TP2082 | Dual Op-Amp | Low power | | TP2092 | Dual Op-Amp | High bandwidth | | TP2231 | Dual Op-Amp | Low noise | | TP2232 | Dual Op-Amp | Low power | ### Comparators (TP1xxx, TP2xxx) | Series | Type | Key Features | |--------|------|--------------| | TP1561 | Comparator | Low power | | TP2345 | Comparator | Fast response | | TP1393 | Comparator | Open-drain output | | TP2393 | Dual Comparator | Open-drain | ### LDO Voltage Regulators (TP7xxx) | Series | Type | Key Features | |--------|------|--------------| | TP7140 | LDO | Low dropout | | TP7150 | LDO | Ultra-low noise | ### ADCs (TP5xxx) | Series | Type | Key Features | |--------|------|--------------| | TP5551 | ADC | Delta-sigma | | TP5854 | ADC | High precision | ### Current Sense Amplifiers (TP1xx) | Series | Type | Key Features | |--------|------|--------------| | TP181 | Current Sense | High-side sensing | | TP182 | Current Sense | Bidirectional | --- ## Handler Implementation Notes ### Component Type Detection The handler distinguishes between similar-looking part numbers: ```java // Op-amps have 4-digit part numbers (TP1541, TP2111) // Current sense amps have 3-digit part numbers (TP181, TP182) // Comparators share prefix but have specific part numbers (TP1561, TP2345) // CRITICAL: Comparators must be excluded from op-amp detection if (COMPARATOR_PATTERN.matcher(mpn).matches()) { return false; // Not an op-amp } ``` ### Package Code Extraction ```java // Package code is the 2-letter suffix after the part number // TP1541-TR -> TR = SOT-23 // TP7150MR -> MR = MSOP (no hyphen variant) // Remove voltage options before extracting package String baseMpn = upperMpn.replaceAll("-[0-9]+$", ""); ``` ### Series Extraction ```java // Current sense amps: TP18x -> "TP18" // Standard 4-digit: TP1541 -> "TP1" // Standard 4-digit: TP7150 -> "TP7" if (upperMpn.matches("^TP18[0-9].*")) { return "TP18"; // Special case for current sense } ``` --- ## Related Files - Handler: `manufacturers/ThreePeakHandler.java` - Component types: `OPAMP`, `VOLTAGE_REGULATOR`, `IC` --- ## Series Descriptions | Series | Description | |--------|-------------| | TP1 | Op-Amps/Comparators | | TP2 | Precision Op-Amps/Comparators | | TP5 | ADCs | | TP7 | LDO Regulators | | TP18 | Current Sense Amplifiers | --- ## Voltage Options (LDO Regulators) LDO regulators often have voltage options encoded as suffix: | Suffix | Output Voltage | |--------|---------------| | -5 | 5.0V | | -33 | 3.3V | | -25 | 2.5V | | -18 | 1.8V | | -12 | 1.2V | --- ## Learnings & Edge Cases - **3-digit vs 4-digit parts**: TP181 (3-digit) is current sense amplifier, TP1541 (4-digit) is op-amp - **Comparator exclusion**: TP1561 and TP2345 are comparators, NOT op-amps, despite similar prefixes - **Package code hyphen**: Both `TP1541-TR` and `TP1541TR` formats are valid - **Voltage option suffix**: `-33` means 3.3V output, not package variation <!-- Add new learnings above this line -->
