The 17 V maximum supply voltage accommodates common USB-C PD adapters and 5 V/9 V/12 V wall warts, but the input over-voltage protection threshold must be set via I²C to clamp before the internal FET sees the full 17 V. Over-current, over-temperature, and over-voltage fault protection are integrated, reducing external component count for the protection network. ## Charge current and input voltage limits The 4.5 A maximum charge current is a continuous rating for a single cell with a 4.2 V battery pack voltage. The current is programmed via I²C, not a resistor — the firmware must set the charge current register before enabling charging. This is a single-cell charger only — the Number of Cells field is 1. It cannot be used for a 2-cell battery pack without external balancing circuitry, and the 4.2 V battery pack voltage confirms the chemistry target. For new designs, this is a safe selection — no imminent obsolescence risk. Cut tape (CT) is also listed for prototype quantities. The datasheet layout recommendation calls for multiple vias under the pad to a ground plane. Surface-mount assembly is standard; the MSL rating (not in evidence) should be verified for reflow profile. The I²C interface uses standard 100 kHz or 400 kHz bus speeds.","metaTitle":"BQ24193RGET Texas Instruments Li-Ion Battery Charger IC","metaDescription":"BQ24193RGET from Texas Instruments: single-cell Li-Ion/Polymer charger, 4.5A max charge current, I²C programmable, 17V input, active production, 24-VQFN","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"24-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24193","Battery Pack Voltage":"4.2V","Charge Current - Max":"4.5A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"17V","Supplier Device Package":"24-VQFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1200","priceTiers":[{"qty":1,"price":"$5.12000","currency":"USD"},{"qty":10,"price":"$4.60200","currency":"USD"},{"qty":25,"price":"$4.35040","currency":"USD"},{"qty":100,"price":"$3.77020","currency":"USD"},{"qty":250,"price":"$3.57688","currency":"USD"},{"qty":500,"price":"$3.20952","currency":"USD"},{"qty":1250,"price":"$2.73600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0ba46c451542f8470b9689a9e833368a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24193RGET/alternatives.json"},"ai":{"faq":[{"question":"Does BQ24193RGET support 4.5 A charge current continuously?","answer":"Yes, the maximum charge current is rated at 4.5 A."},{"question":"Can I use BQ24193RGET for a 2-cell battery pack?","answer":"No, the BQ24193RGET is a single-cell charger with a 4.2 V battery pack voltage.
