It also fits cleanly into PoE systems and battery-management applications where bidirectional I²C isolation across high-voltage barriers is required.\u003c\/p\u003e\n\u003ch3\u003e5kVrms Isolated I²C Chip for Reliable Antminer Bitmain PSU Repairs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect replacement\u003c\/strong\u003e for damaged APW17 PSU components — drop-in for the original footprint.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-high insulation\u003c\/strong\u003e — 3.75kVrms and 5kVrms options for high-voltage isolation barriers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow power consumption\u003c\/strong\u003e — 1.5mA per channel at 1Mbps keeps drive losses under control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide operating temperature range\u003c\/strong\u003e — -40°C to +125°C for harsh mining-farm conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced EMC performance\u003c\/strong\u003e — ESD, EFT, and surge-resistant for reliable continuous duty.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNSi8100N Use Cases Beyond APW17\u003c\/h3\u003e\n\u003cp\u003eThe same combination of high CMTI, low propagation delay (\u0026lt;15ns), and ±6kV ESD protection (HBM) makes the NSi8100N an excellent choice for PoE systems, industrial battery management, and any mixed-voltage I²C bus where galvanic isolation is required. The 2.5V to 5.5V supply range covers most modern logic rails directly, and the bidirectional capability simplifies layout when both controller and target devices need to communicate across the isolation barrier.\u003c\/p\u003e\n\u003ch4\u003eNSi8100N Isolator Chip Specifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eFeature\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eInsulation Voltage\u003c\/td\u003e\n\u003ctd\u003eUp to 5000Vrms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eI²C Clock Frequency\u003c\/td\u003e\n\u003ctd\u003eUp to 2MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e2.5V to 5.5V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCMTI\u003c\/td\u003e\n\u003ctd\u003e150kV\/μs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eESD Protection (HBM)\u003c\/td\u003e\n\u003ctd\u003e±6kV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e1.5mA\/ch (1Mbps)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePropagation Delay\u003c\/td\u003e\n\u003ctd\u003e\u0026lt;15ns\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40°C to 125°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated products\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/si8261-si8261bbd-isolator-gate-drivers-cryptominer-repair\"\u003eSI8261BBD 5kV Gate Driver – Whatsminer P21 PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/ltv-817c-optocoupler-isolator-5kv-bitmain-apw8-apw9-apw17-psu\"\u003eLTV-817C Optocoupler – APW8\/APW9\/APW17 PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/stp6n95k5-mosfet-power-transistor-bitmain-apw12-psu\"\u003eSTP6N95K5 950V MOSFET – APW12 PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/ixfp4n85x-850v-n-channel-mosfet-mining-psu-dc-converter\"\u003eIXFP4N85X 850V MOSFET – Mining PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAPW17 repair shops ordering NSi8100N in volume can email \u003ca href=\"mailto:contact@lys-sz.com\"\u003econtact@lys-sz.com\u003c\/a\u003e for bulk pricing and matched PSU repair kits.
