MAX77705F Power Management IC for Samsung Galaxy Phones
Replace a confirmed faulty MAX77705F power-management integrated circuit on selected Samsung Galaxy logic boards with this board-level component. This listing is for one bare IC only. It is intended for experienced microsoldering technicians with the diagnostic equipment, rework tools and board knowledge needed to remove and replace a surface-mounted chip safely.
The JPC stock record identifies this component by SKU IC-212 and chip marking MAX77705F. During this review, exact-SKU, exact-chip, full-title and Crazy Parts Board Components menu searches did not locate a current matching supplier listing. JPC still records five units in local Shopify stock, so the product remains active while those units are available. Supplier replenishment and backorder availability are not promised.
Key details
-
Chip reference: MAX77705F.
-
Function category: Power-management IC for compatible Samsung Galaxy logic boards.

-
Microsoldering required: Removal, pad preparation, alignment, reflow and post-repair testing require specialist equipment and experience.

Part only: No phone, logic board, tools, stencil, solder, labour or diagnosis is included.
Compatibility listed for this stock item
- Samsung Galaxy S9, including the G960F family where the original board uses MAX77705F
- Samsung Galaxy S9 Plus, including the G965F family where the original board uses MAX77705F
- Samsung Galaxy S10 Plus, including the G975F family where the original board uses MAX77705F
- Samsung Galaxy Note 9, including the N960F family where the original board uses MAX77705F
Compatibility at board level depends on the exact device submodel, board revision, original chip marking and circuit location. A model name alone is not enough to confirm that this IC is suitable. Compare the marking on the original component, consult an appropriate board schematic or parts reference, and inspect the board before ordering.
Australian and international sellers use slightly different compatibility wording for MAX77705F. Some list only Galaxy S9 and S9 Plus, while specialist board-component catalogues also reference Galaxy S10 Plus and Note 9 families. This page retains the four families already attached to the JPC stock record but does not promise every regional, carrier or board revision. It does not extend compatibility to unrelated Galaxy models merely because a similar fault or chip family is mentioned elsewhere.
Diagnose the board first
No-power, charging, abnormal current draw, unstable boot or heat-related symptoms can have many causes. Possible faults include the battery, charging port, charging-port board, flex cables, damaged connectors, shorted capacitors, corroded components, USB controller circuitry, power-management rails, board separation, liquid damage or software. Replacing the MAX77705F without confirming the fault can leave the original problem unchanged or cause additional board damage.
Use appropriate diagnostic methods before removal. These may include visual inspection, diode-mode measurements, resistance checks, current-consumption analysis, thermal observation and comparison with known-good board data. Follow device-specific circuit information available to a qualified technician. This product page is not a repair procedure and is not a substitute for board-level training.
Installation requirements
This is not a plug-in component. Installation requires precision board work and may involve shielding removal, controlled preheating, hot-air rework, solder preparation, accurate alignment and inspection under magnification. Excessive temperature, airflow, pressure or rework time can dislodge nearby components, damage pads, warp the board or affect underfilled components.
Protect heat-sensitive parts and document component orientation before removal. Prepare pads without removing copper or solder mask, confirm that the replacement aligns naturally, and inspect all connections after reflow. Appropriate fume extraction, eye protection and electrostatic precautions should be used. Stop if the board is bent, corroded, delaminated or otherwise unsuitable for repair.
After installation, check for shorts before applying power. Test power-up, charging behaviour, current draw, thermal response and all related device functions before final assembly. A successful solder joint does not prove that the original diagnosis was correct, so complete functional testing remains necessary.
Condition and identification
The exact current Crazy Parts listing could not be verified, so this page does not claim current supplier stock, a supplier test process, supplier warranty, grade, country of origin or global barcode. The component is identified by the existing local stock record, SKU IC-212 and MAX77705F marking. Inspect the item before installation and compare it with the original board component.
No claim is made that this IC will resolve every power or charging fault, that it is suitable for every board revision, or that installation is risk-free. Product imagery is for identifying the supplied component. Small production markings can vary, and the physical item should be checked before irreversible installation work begins.

Choosing the correct component
Check the original IC marking before ordering. Similar-looking Samsung power-management and charging ICs are not automatically interchangeable. Device names can cover multiple regional models and production revisions, and a replacement selected only from a symptom may be wrong. If the original marking cannot be read, use board documentation and circuit-level measurements to identify the failed component before purchase.
This listing describes a replacement part, not a guaranteed repair result. Installation success depends on correct diagnosis, compatible board revision, the condition of surrounding circuitry and professional workmanship. If you are not equipped for BGA or fine-pitch IC rework, arrange installation through a suitably experienced repair technician.
Availability
This product remains active because JPC records five units in local Shopify stock. The variant is configured to stop selling when local inventory reaches zero. Crazy Parts exact-SKU and manual catalogue checks did not confirm a current replenishment source, so customers should not expect supplier-order fulfilment after the recorded local units sell.
Warranty and Australian Consumer Law
No current supplier warranty was verified for this exact stock item during the live supplier review, and no additional or voluntary JPC Mobile warranty is stated on this page. Board-level components can be damaged by incorrect diagnosis, electrostatic discharge, excessive heat, poor alignment, pad damage, liquid exposure or other installation factors.
Nothing on this page excludes, restricts or modifies any consumer guarantee, right or remedy that cannot lawfully be excluded under the Australian Consumer Law. Consumer rights apply independently of whether a separate supplier or voluntary warranty is offered.
Frequently asked questions
Is this a complete charging port or logic board?
No. It is one bare MAX77705F integrated circuit for board-level repair.
Can I install it without microsoldering equipment?
No. Specialist rework tools, magnification, diagnosis and board-level experience are required.
Will it fix a Samsung phone that will not power on?
Only if this IC is correctly diagnosed as the cause and the rest of the device is repairable. Many other faults can produce similar symptoms.
Can JPC order more when the five units sell?
No current exact Crazy Parts source was verified, so supplier replenishment is not promised.
Is installation included?
No. The listed price is for the IC only.
