The I²C interface handles charge current programming, timer settings, and status monitoring — no external resistors for current setpoint. ## Charge parameters and protection Maximum charge current is 1.55 A, programmable via I²C; the battery pack voltage ceiling is 4.44 V. Over-temperature and over-voltage fault protection are built in — the charger enters a safe state without external supervisory circuitry. Operating temperature range is -30°C to 85°C, covering most portable and industrial battery-powered equipment. Supply voltage max is 9 V, so a 5 V USB rail or a 9 V wall adapter both work.","metaTitle":"BQ24156AYFFR Li-Ion/Polymer Charger, I²C, 1.55 A, 20-DSBGA","metaDescription":"Texas Instruments BQ24156AYFFR single-cell Li-Ion/Polymer charger with I²C interface, 1.55 A max charge current, 4.44 V pack voltage, over-temp/over-voltage","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"20-UFBGA, DSBGA","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24156","Battery Pack Voltage":"4.44V (Max)","Charge Current - Max":"1.55A","Operating Temperature":"-30°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"9V","Supplier Device Package":"20-DSBGA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6750","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fbbe353cead52b139a4ac88ab3e630e0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BQ24156AYFFR charge a 2-cell battery?","answer":"No — it is designed for single-cell Li-Ion/Polymer packs only.
