The I²C interface lets the host adjust current, timer, and voltage dynamically — useful for implementing fast-charge profiles or thermal-throttling algorithms without hardware changes. ## 18V input, 4.8V battery ceiling, industrial temp range The charger accepts a maximum supply voltage of 18V, covering USB-C PD adapters and 5V/9V/12V wall warts. The battery pack voltage tops out at 4.8V — that's the termination ceiling for a single Li-ion cell, not a multi-cell stack. ## Built-in fault protections reduce external BOM On-chip fault protection covers over-current, over-temperature, over-under voltage, and short-circuit conditions. That means fewer external sense resistors, comparators, or supervisory ICs on the board — a clean single-chip charge path. ## Active production, 18-WQFN package, tape-and-reel It ships in Tape & Reel (TR) or Cut Tape (CT) in an 18-PowerWFQFN package with a supplier device package of 18-WQFN-HR measuring 3x2.5 mm.","metaTitle":"BQ25629RYKR – TI I²C-Controlled Single-Cell Li-Ion Charger","metaDescription":"BQ25629RYKR from Texas Instruments: I²C-programmable single-cell Li-ion/polymer charger, 18V max input, 2A charge current, industrial temp range, 18-WQFN","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"18-PowerWFQFN","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over-Under Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"4.8V (Max)","Charge Current - Max":"2A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"18V","Supplier Device Package":"18-WQFN-HR (3x2.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1500","priceTiers":[{"qty":1,"price":"$4.15000","currency":"USD"},{"qty":10,"price":"$3.72600","currency":"USD"},{"qty":25,"price":"$3.52240","currency":"USD"},{"qty":100,"price":"$3.05270","currency":"USD"},{"qty":250,"price":"$2.89616","currency":"USD"},{"qty":500,"price":"$2.59872","currency":"USD"},{"qty":1000,"price":"$2.19170","currency":"USD"},{"qty":3000,"price":"$1.43733","currency":"USD"},{"qty":6000,"price":"$1.38330","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/23e974d5c4d146983373ac41773135ef.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ25629RYKR/alternatives.json"},"ai":{"faq":[{"question":"Does BQ25629RYKR support fast charging?","answer":"Yes — the programmable charge current up to 2A and I²C-controlled voltage/timer allow implementation of fast-charge profiles such as CC-CV with adjustable termination current.
