It integrates a constant-current programmable charge controller with a maximum charge current of 1A, over-temperature and over-voltage fault protection, and operates from a supply up to 10.2V. ## Chemistry and voltage match This part is specifically tailored for LiFePO4 cells with a battery pack voltage of 3.5V. It is not a general-purpose Li-ion or LiPo charger — those chemistries require a different termination voltage. The USB interface means the input can come directly from a USB port or a 5V regulated supply. ## Package and mounting Housed in a 10-WFDFN exposed pad package (10-WSON 3x2 mm), the BQ25070DQCT is a surface-mount device.","metaTitle":"BQ25070DQCT LiFePO4 charger IC, USB, 1A, 10-WSON","metaDescription":"Texas Instruments BQ25070DQCT is a single-cell LiFePO4 battery charger with USB interface, 1A max charge current, over-temp/over-voltage protection, 10-WFDFN","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":"USB","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Iron Phosphate","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25070","Battery Pack Voltage":"3.5V","Charge Current - Max":"1A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"10.2V","Supplier Device Package":"10-WSON (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/7d9661f22fe3a7628c04268cd90021e4.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ25070DQCT compatible with 3.7V Li-ion batteries?","answer":"No. The BQ25070DQCT is designed for Lithium Iron Phosphate (LiFePO4) cells with a 3.5V pack voltage.
