It generates the drive signals for the half-bridge MOSFETs at the precise timing and frequency needed for soft-switching. Voltage transients, thermal runaway in the driver stage or capacitive-mode events during severe overload can damage the controller IC. A failed LLC controller causes the PSU to produce no output or oscillate erratically, often accompanied by audible buzzing from the power transformer.\u003c\/p\u003e\n\u003ch3\u003eReplacement Procedure\u003c\/h3\u003e\n\u003cp\u003eDisconnect mains and discharge all capacitors. Locate the HR1001A on the primary control board — it is a 16-pin SOIC near the gate drive transformer or bootstrap circuit. Desolder, clean pads, install the new IC with pin 1 aligned and reflow. If the controller failure caused MOSFET damage, replace the power MOSFETs as well. Power through a variac under progressive load and verify clean, stable output.\u003c\/p\u003e\n\u003ch4\u003eHR1001A LLC Controller Specifications\u003c\/h4\u003e\n\u003ctable style=\"width: 100%; height: 171px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003eHR1001A (MPS1745)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eTopology\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003eLLC resonant converter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eMax Frequency\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003e600kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eHigh-Side Driver\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003e600V with bootstrap diode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eProtections\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003eADTA, CMP, 2-level OCP, OTP, auto-recovery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eDuty Cycle\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003e50%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003ePackage\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003eSOIC-16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 24.777561%; height: 19px;\"\u003eCondition\u003c\/td\u003e\n\u003ctd style=\"text-align: left; padding: 6px 12px; width: 64.808485%; height: 19px;\"\u003eNew\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003e\u003c\/h3\u003e\n\u003ch3\u003eRelated PSU Controller ICs \u0026amp; Components\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/products\/l6599dtr-l6599d-l6599-power-supply-resonant-controller-bitmain-avalon-psu\"\u003eL6599D LLC Resonant Controller – Bitmain \/ Avalon PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/da08025b12ug-power-supply-cooling-fan-8cm-microbt-whatsminer-p21-psu-cooler\"\u003eDA08025B12UG 80mm Fan – Whatsminer P21 PSU Cooler\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/ipw65r029cfd7-65r029f7-mosfet-whatsminer-p222b-p221b-power-supply-psu-repair\"\u003eIPW65R029CFD7 MOSFET – Whatsminer P222B \/ P221B PSU\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/products\/18p-data-cable-whatsminer-m21b-psu-power-supply-connection\"\u003e18P Data Cable – Whatsminer PSU Connection\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eRepairing Whatsminer PSU control stages? \u003ca href=\"mailto:contact@lys-sz.com\"\u003eContact us at contact@lys-sz.com\u003c\/a\u003e for LLC controllers, gate drivers and matched MOSFETs.\u003c\/p\u003e\n\u003cp\u003eWorldwide shipping from our Shenzhen warehouse.\u003c\/p\u003e","brand":"LYS Shenzhen","offers":[{"title":"Default Title","offer_id":43024385310899,"sku":null,"price":0.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0627\/6710\/4179\/files\/HR1001A-MPS1745-Enhanced-LLC-Controller-Whatsminer-Power-Supply-Repair.webp?v=1744701413","url":"https:\/\/lys-sz.com\/products\/hr1001a-mps1745-llc-controller-whatsminer-power-supply-repair","provider":"LYS Shenzhen","version":"1.0","type":"link"}
