The charge current is programmable up to 656 mA maximum, and the IC includes over-voltage fault protection to guard the battery and the charging circuit against supply transients. ## Package and temperature range Housed in an 8-WFDFN Exposed Pad package (8-TDFN-EP, 2x2 mm), surface-mount assembly requires a thermal pad connection on the PCB to dissipate heat from the charging pass element. ## Supply voltage and protection Maximum supply voltage is 6.8 V, which means the charger can run from a standard 5 V USB bus or a regulated 5 V rail with headroom for the internal linear regulator. The over-voltage protection block disconnects the battery if the input exceeds a safe threshold, preventing damage to the cell and the downstream load.","metaTitle":"MAX8814ETA+T Li-Ion Charger IC, 8-TDFN, Active","metaDescription":"Analog Devices MAX8814ETA+T single-cell Li-Ion charger IC. 656 mA max charge current, over-voltage protection, 8-WFDFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"4.2V","Charge Current - Max":"656mA","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"6.8V","Supplier Device Package":"8-TDFN-EP (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.01","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.01000","currency":"USD"},{"qty":10,"price":"$4.49800","currency":"USD"},{"qty":25,"price":"$4.25240","currency":"USD"},{"qty":100,"price":"$3.68550","currency":"USD"},{"qty":250,"price":"$3.49648","currency":"USD"},{"qty":500,"price":"$3.13740","currency":"USD"},{"qty":1000,"price":"$2.83500","currency":"USD"},{"qty":2500,"price":"$2.65500","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for MAX8814ETA+T?","answer":"The maximum programmable charge current is 656 mA, suitable for single-cell Li-Ion batteries in the 500–700 mAh range."},{"question":"What package does MAX8814ETA+T use?","answer":"It uses an 8-WFDFN Exposed Pad package (8-TDFN-EP, 2x2 mm) for surface-mount assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX8814ETA~3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX8814ETA~3T when reusing this data.
