Its 500 mA maximum charge current suits portable devices where charge time is balanced against thermal budget in a small 3x3 mm QFN. The part integrates fault protection against over-temperature, over-voltage, reverse current, and short-circuit conditions — covering the common failure modes when a USB cable is hot-plugged or the battery is reversed. Operating junction temperature spans -40°C to 125°C, so it can sit on a board near a hot processor or inside an outdoor enclosure without derating. ## Supply and charge-current boundaries Maximum supply voltage is 6.4V — typical USB VBUS is 5V, but the 6.4V ceiling gives headroom for transients on the bus. If the input exceeds that, the over-voltage protection shuts down the charger. Charge current is constant and programmable via an external resistor. The 500 mA max is the ceiling; you set a lower current if the upstream USB port or thermal environment demands it. Battery regulation voltage is 4.2V — the standard termination for a single Li-ion cell. The timer-based programmable feature ends the charge cycle after a set period, preventing overcharge if the cell never reaches the termination voltage. ## Active production and package options It is a current-design part, safe to specify for new builds. Supplied in Tape & Reel (TR) or Cut Tape (CT), both surface-mount on the 16-VFQFN exposed-pad package.","metaTitle":"BQ24230RGTT Texas Instruments Li-Ion Charger IC – Active","metaDescription":"BQ24230RGTT from Texas Instruments: single-cell Li-Ion charger, USB interface, 500mA max charge current, 6.4V supply max, -40°C to 125°C, 16-VQFN (3x3) package.","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":"USB","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","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":"$2.7600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/44973b3b06f1e897d62883646ccf9c29.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current of the BQ24230RGTT?","answer":"500 mA.
