It handles both lithium-ion/polymer and lithium iron phosphate (LiFePO4) chemistries, with a programmable charge current up to 800 mA and a battery termination voltage up to 4.4 V. ## Charge current and thermal limits in the 2x2 WSON Maximum charge current is 800 mA, constant-current programmable via an external resistor. In the 8-WSON (2x2 mm) package with exposed pad, the thermal design must sink about 0.5 W at full current from a 5 V input to a 3.7 V cell. ## Integrated fault protection and programmable features Overcurrent, overvoltage, overtemperature, and short-circuit protection are built in, reducing external supervisory circuitry. Three programmable parameters — charge current, timer, and termination voltage — let the BOM tune the charge profile to the specific cell type without firmware changes.","metaTitle":"BQ25170JDSGR 1S Li-Ion/LiFePO4 Charger, 800mA, 8-WSON","metaDescription":"Texas Instruments BQ25170JDSGR linear charger IC for 1-cell Li-Ion, Li-Pol, and LiFePO4 packs.","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)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer, Lithium Iron Phosphate","Current - Charging":"Constant - Programmable","Base Product Number":"BQ25170","Battery Pack Voltage":"4.4V (Max)","Charge Current - Max":"800mA","Operating Temperature":"-40°C ~ 125°C (TJ)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"6.6V","Supplier Device Package":"8-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3676","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b390078fcaa124b055eede2c28f90809.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ25170JDSGR compatible with LiFePO4 batteries?","answer":"Yes.
