The charge current and charge-termination timer are both programmable via external resistors, giving the designer control over the charge profile without firmware overhead. Over-temperature fault protection shuts down the charger if the die temperature exceeds the safe operating limit, preventing thermal runaway during a fault condition. ## Package and supply voltage — board-fit for portable designs Housed in an 8-MSOP package (3.00 mm width, 0.118\" body width), the ADP2291ARMZ-R7 occupies minimal PCB area and is suited for space-constrained handheld or wearable products. Surface-mount mounting with tape-and-reel or cut-tape packaging supports standard pick-and-place assembly lines. The maximum supply voltage of 12 V allows direct connection to common USB power sources (5 V) or wall adapters without an additional pre-regulator.","metaTitle":"ADP2291ARMZ-R7 Li-Ion Battery Charger IC, 1.5A, 8-MSOP","metaDescription":"ADP2291ARMZ-R7 single-cell Li-Ion charger IC, 1.5A max charge current, 4.2V battery pack voltage, over-temperature protection, -40°C to 85°C, 8-MSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"12V","Supplier Device Package":"8-MSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.89","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.89000","currency":"USD"},{"qty":10,"price":"$4.39000","currency":"USD"},{"qty":25,"price":"$4.15000","currency":"USD"},{"qty":100,"price":"$3.59660","currency":"USD"},{"qty":250,"price":"$3.41216","currency":"USD"},{"qty":500,"price":"$3.06170","currency":"USD"},{"qty":1000,"price":"$2.61000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current and battery voltage for ADP2291ARMZ-R7?","answer":"The maximum charge current is 1.5 A, and the battery regulation voltage is 4.2 V for a single-cell lithium-ion pack."},{"question":"What package does ADP2291ARMZ-R7 come in?","answer":"It is supplied in an 8-MSOP package (3.00 mm width, 0.118\" body width), surface-mount, available in tape-and-reel or cut-tape formats."},{"question":"What compliance documentation is available for ADP2291ARMZ-R7?","answer":"The part is ROHS3 compliant.
