It handles 1 to 2 series cells with a maximum charge current of 2A and a battery pack voltage of 8.4V — the termination voltage for a 2S Li-ion stack. Fault protection includes over-temperature and over-voltage shutdown, and the charge current and timer are programmable via external components. The 16V maximum supply voltage covers common 5V USB and 12V wall-adapter inputs. ## Temperature grade and package details The 20-VFQFN Exposed Pad package (20-VQFN, 3.5x4.5 mm body) requires a thermal land on the PCB for heat dissipation. No official second-source or cross-reference is listed, but the bqSWITCHER family includes functionally similar chargers with different cell counts or current ratings.","metaTitle":"BQ24103RHLR TI bqSWITCHER™ Li-Ion Charger IC, 2A, 20-VQFN","metaDescription":"Texas Instruments BQ24103RHLR Li-Ion/Polymer charger IC, 1-2 cells, 2A max charge current, 8.4V pack voltage, active production. 20-VQFN package.","metaKeywords":null},"attributes":{"series":"bqSWITCHER™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqSWITCHER™","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1 ~ 2","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24103","Battery Pack Voltage":"8.4V","Charge Current - Max":"2A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.7000","priceTiers":[{"qty":1,"price":"$5.70000","currency":"USD"},{"qty":10,"price":"$5.12100","currency":"USD"},{"qty":25,"price":"$4.84160","currency":"USD"},{"qty":100,"price":"$4.19600","currency":"USD"},{"qty":250,"price":"$3.98084","currency":"USD"},{"qty":500,"price":"$3.57198","currency":"USD"},{"qty":1000,"price":"$3.04500","currency":"USD"},{"qty":3000,"price":"$3.04500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/26d08c6a9886ba7ed4911c20d19d787e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24103RHLR/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24103RHLR compatible with 2-cell Li-Polymer batteries?","answer":"Yes. The battery pack voltage is 8.4V, which is the standard termination voltage for two Li-ion or Li-Polymer cells in series. The charger supports 1 to 2 cells, so a 2S pack is within the specified range."},{"question":"What is the difference between BQ24103RHLR and the base BQ24103?","answer":"The BQ24103 is the base product number for the die. The RHLR suffix specifies the 20-VQFN (3.5x4.5 mm) package and reel packaging. The silicon is identical; the difference is only in package and delivery form."},{"question":"Can BQ24103RHLR charge a single 3.7V cell?","answer":"Yes, the charger supports 1 to 2 cells. For a single 3.7V Li-ion cell, the termination voltage is typically 4.2V, which is within the charger's programmable range. The battery pack voltage of 8.4V is the maximum for 2 cells; for a single cell the regulation voltage is set lower via the external resistor divider."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24103RHLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24103RHLR when reusing this data.
