It accepts power from a USB port and delivers a programmable constant charge current up to 1 A, with a regulated float voltage of 4.2 V. On-chip fault protection covers over-voltage, over-temperature, and short-circuit conditions — no external supervisor is required for the basic safety envelope. ## Charge current and thermal budget The 1 A maximum charge current is set via an external resistor — the constant-current loop is programmable, so the BOM engineer tailors the charge rate to the cell capacity. For a 500 mAh cell, a 0.5 C rate (500 mA) keeps the die temperature rise manageable in a sealed enclosure. ## Protection set and supply range The protection block monitors the input for over-voltage, the die for over-temperature, and the output for short-circuit — all three trip thresholds are fixed on-chip. The maximum supply voltage is 6.45 V, which covers a standard 5 V USB bus with margin for cable droop and hot-plug transients. No external OVP FET is needed for the USB input. ## Package and footprint notes The BQ24092DGQR is offered in a 10-PowerTFSOP / 10-MSOP package with a body width of 0.118 inches (3.00 mm). The PCB layout must include a thermal land and via array under the pad; the recommended footprint is in the TI datasheet. ## Sourcing and lifecycle posture No official second-source or cross-reference is listed in the TI documentation, so dual-sourcing depends on a functionally equivalent part from another vendor.","metaTitle":"BQ24092DGQR Li-Ion Charger IC, 1A Max, USB Interface, Active","metaDescription":"Texas Instruments BQ24092DGQR single-cell Li-Ion/Polymer charger IC. 1A programmable charge current, USB input, over-voltage/thermal/short-circuit protection.","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":"10-PowerTFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24092","Battery Pack Voltage":"4.2V","Charge Current - Max":"1A","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"Current","Voltage - Supply (Max)":"6.45V","Supplier Device Package":"10-HVSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdee6fb711b7ffa38d45fa435662349c.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24092DGQR an equivalent to BQ24090?","answer":"The BQ24092 and BQ24090 are both single-cell Li-ion linear chargers from TI with a USB interface and a 1 A maximum charge current. The primary difference is the package: the BQ24092DGQR comes in a 10-HVSSOP, while the BQ24090 is typically offered in a different package variant. Pin compatibility depends on the specific package option — confirm the pinout against your layout before substituting."},{"question":"Does BQ24092DGQR have overvoltage protection?","answer":"Yes, the BQ24092DGQR includes on-chip over-voltage protection as part of its fault-protection block. It also monitors for over-temperature and short-circuit conditions — all three are handled internally without external components."},{"question":"What is the maximum charge current of BQ24092DGQR?","answer":"The maximum charge current is 1 A. The charge current is programmable via an external resistor, so the actual charge rate is set by the BOM resistor value — the 1 A figure is the upper limit of the constant-current loop."},{"question":"What package does BQ24092DGQR come in?","answer":"The BQ24092DGQR is supplied in a 10-PowerTFSOP / 10-MSOP package with a body width of 0.118 inches (3.00 mm)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24092DGQR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24092DGQR when reusing this data.
