It delivers a constant charge current up to 500 mA and terminates at a 4.1V battery regulation voltage — the chemistry sweet spot for many 4.2V-rated cells that charge to 4.1V for extended cycle life. ## Programmable current and timer — set the charge profile Two programmable features — charge current and charge timer — let you tailor the charge algorithm without changing the IC. The current is set with an external resistor; the timer provides a safety timeout that terminates charging if the battery does not reach the regulation voltage within the window. This is a linear charger, so the input supply must stay above the battery voltage by the dropout margin; the maximum supply voltage is 13.5 V. ## Fault protection and temperature range Built-in fault protection covers over-temperature and short-circuit conditions on the output. ## Package and mounting — 8-HVSSOP with exposed pad The pad also provides a solid ground reference.","metaTitle":"BQ24203DGNG4 Li-Ion Charger IC, 500mA Max, 4.1V, Active","metaDescription":"Texas Instruments BQ24203DGNG4 single-cell Li-Ion/Polymer charger IC. 500mA max charge current, 4.1V pack voltage, programmable current/timer.","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":"Tube","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ24203","Battery Pack Voltage":"4.1V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"13.5V","Supplier Device Package":"8-HVSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8d269c85a61d814b6ccabe42b85d2ae7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24203DGNG4 suitable for charging 4.2V lithium-ion batteries?","answer":"Yes, with a note. The BQ24203DGNG4 regulates the battery pack voltage to 4.1V, which is within the safe charging range for most 4.2V-rated Li-Ion cells. Charging to 4.1V instead of 4.2V reduces capacity slightly (roughly 10-15%) but extends cycle life. If you need the full 4.2V termination, look at a charger with a 4.2V regulation point."},{"question":"What is the charge current range and programmability for BQ24203DGNG4?","answer":"The maximum charge current is 500 mA, and the charge current is programmable via an external resistor. The charge timer is also programmable. The IC operates in constant-current mode during the bulk charge phase."},{"question":"What is the difference between BQ24203DGNG4 and BQ24203?","answer":"The BQ24203DGNG4 is the specific ordering code for the 8-HVSSOP package variant with tape-and-reel packaging. The base part number BQ24203 refers to the die and function; the DGNG4 suffix identifies the package and shipping format. Functionally they are identical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24203DGNG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24203DGNG4 when reusing this data.
