That 500 mA ceiling is the first decision point: it fits small-form-factor devices with batteries in the 300–800 mAh range—think Bluetooth headsets, wearable trackers, or portable medical sensors. If your BOM calls for charging a 2000 mAh cell in under three hours, this part is not the one; you need a switch-mode charger with higher current. The constant-current phase is programmable via an external resistor, so you can dial it down to match a smaller cell without overstressing it. ## Protection set: what is covered and what is not The charger integrates over-temperature, over-voltage, reverse-current, and short-circuit fault protection. That covers the common failure modes in a single-cell Li-Ion system: a shorted battery terminal, a reversed input supply, or a charger that runs hot in a sealed enclosure. What it does not include is a dedicated battery NTC thermistor input for JEITA-compliant temperature monitoring—if your design requires that, you need an external thermistor circuit or a different charger IC. ## Package and thermal reality The 16-VFQFN with exposed pad (3x3 mm body) is the package. The 0.50 mm pitch demands a 4-layer board for reliable fan-out; two-layer designs risk lifting the corner pads during reflow.","metaTitle":"BQ24230RGTRG4 Li-Ion Charger IC, 500 mA Max, USB Interface","metaDescription":"Texas Instruments BQ24230RGTRG4 single-cell Li-Ion charger IC with 500 mA max charge current, USB interface, fault protection, -40°C to 125°C range.","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":"16-VFQFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24230","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Timer","Voltage - Supply (Max)":"6.4V","Supplier Device Package":"16-VQFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/44973b3b06f1e897d62883646ccf9c29.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of BQ24230RGTRG4?","answer":"The maximum charge current is 500 mA, programmable via an external resistor."},{"question":"What battery chemistries does BQ24230RGTRG4 support?","answer":"It supports single-cell Lithium Ion (Li-Ion) batteries with a 4.2 V full-charge voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24230RGTRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24230RGTRG4 when reusing this data.
