It also absorbs the input ripple from a noisy automotive rail or a flyback supply without needing a pre-regulator. The integrated fault protection — overcurrent, overtemperature, and overvoltage — shuts down the charge cycle before the silicon or the battery sees stress, so the designer can skip the discrete protection clamp on the input. ## Temperature grade and package — deployment fit Surface-mount only; the Tape & Reel option suits automated pick-and-place for volume builds.","metaTitle":"BQ24170RGYT Li-Ion Charger IC, 4A, 1-3 Cells, 24-VQFN","metaDescription":"Texas Instruments BQ24170RGYT is a 4A programmable Li-Ion/Polymer charger for 1-3 cells.","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":"-","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1 ~ 3","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24170","Battery Pack Voltage":"4.2V","Charge Current - Max":"4A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current","Voltage - Supply (Max)":"17V","Supplier Device Package":"24-VQFN (5.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0430f7feecc292ef9ab6ebeae8cd2668.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can BQ24170RGYT charge a 2S or 3S Li-ion battery?","answer":"Yes.
