Handler Implementation Notes

Package Code Extraction

// Torex package code is the SINGLE LETTER immediately after 4-digit part number
// Pattern: XC[0-9]{4}[PACKAGE-LETTER][VOLTAGE][OPTIONS][SUFFIX]
// Example: XC6206P332MR -> P -> SOT-23-5

// MR/TR at end are tape/reel indicators, NOT package codes
Pattern standardPattern = Pattern.compile("^XC[0-9]{4}([A-Z]).*$");

// Short form like XC61CN - second letter may be package
Pattern shortPattern = Pattern.compile("^XC6[0-9]([A-Z]{2}).*$");

Voltage Code Extraction

// Voltage code is 2-3 digits after package letter
// 332 = 3.32V, 33 = 3.3V, 25 = 2.5V
Pattern voltagePattern = Pattern.compile("^XC[0-9]{4}[A-Z]([0-9]{2,3})[A-Z]?.*$");

public String extractVoltageCode(String mpn) {
    // XC6206P332MR -> 332 -> 3.3V
    Matcher matcher = voltagePattern.matcher(mpn);
    if (matcher.matches()) {
        return matcher.group(1);
    }
    return "";
}

Series Extraction

// Standard format: XC[0-9]{4} -> first 4 chars after XC
// Returns XC62, XC91, XC92, XC61, etc.
if (upperMpn.matches("^XC[0-9]{4}.*")) {
    return upperMpn.substring(0, 4);  // XC62, XC91, etc.
}

// Short format: XC6[0-9][A-Z]{2} -> first 4 chars
if (upperMpn.matches("^XC6[0-9][A-Z]{2}.*")) {
    return upperMpn.substring(0, 4);
}

Product Type Detection

public boolean isLDO(String mpn) {
    return mpn.matches("^XC6[234][0-9]{2}.*");  // XC62xx, XC63xx, XC64xx
}

public boolean isDCDCConverter(String mpn) {
    return mpn.matches("^XC9[123][0-9]{2}.*");  // XC91xx, XC92xx, XC93xx
}

public boolean isVoltageDetector(String mpn) {
    return mpn.matches("^XC61[0-9]{2}.*") ||    // XC61xx
           mpn.matches("^XC61[A-Z]{2}.*");      // XC61CN short form
}

public boolean isBatteryCharger(String mpn) {
    return mpn.matches("^XC68[0-9]{2}.*");      // XC68xx
}

public boolean isLoadSwitch(String mpn) {
    return mpn.matches("^XC81[0-9]{2}.*");      // XC81xx
}

Learnings & Edge Cases

• Ultra-low quiescent current: XC6206 is famous for 1uA Iq, popular in battery applications
• Package letter is SINGLE character: P, A, B, N etc. immediately after 4-digit series number
• Voltage code encoding: 332 = 3.32V, 30 = 3.0V, 25 = 2.5V (first 2 digits are major.minor)
• Short form MPNs: XC61CN uses letter codes instead of numeric series (CN = variant+package)
• MR suffix confusion: MR means Metal Reel + USP package, not just tape/reel
• Voltage detectors (XC61xx): These are reset ICs/supervisors, classified as voltage regulators
• Load switches (XC81xx): Power distribution switches with protection features
• No LED driver support: Unlike other PMIC vendors, Torex handler doesn't include LED drivers
