That 1.2 A ceiling sets the practical charge rate for a 1000–1500 mAh cell in a handheld or portable device — fast enough for a reasonable charge cycle without pushing the thermal limits of the 20-HTSSOP package. The charger operates from a supply up to 10 V max and integrates over-temperature fault protection, which shuts down the pass element if the die temperature exceeds the safe threshold. The programmable features — charge current and charge timer — let the designer set the termination point and a safety timeout via external resistors, no I²C bus required. ## Package and thermal: 20-HTSSOP The BQ24002PWPG4 comes in a 20-PowerTSSOP (0.173-inch width, 4.40 mm body) with an exposed thermal pad on the bottom — the 20-HTSSOP supplier device package. At 1.2 A charge current and a typical input-to-battery dropout of a few hundred millivolts, the power dissipation can reach 0.5–0.8 W, so the PCB copper area under the pad sets the junction temperature. The listed shipping medium is Tube. No reel or tape quantity is specified — expect the standard TI tube count for this package (typically 50 or 75 units per tube, but confirm at quote). The base product number is BQ24002, so pin-compatible variants (e.g. BQ24003) may share the same footprint but differ in charge current or feature set — verify the full order code before substituting.","metaTitle":"Texas Instruments BQ24002PWPG4 Li-Ion Battery Charger IC","metaDescription":"TI BQ24002PWPG4 single-cell Li-Ion charger IC, 1.2A max charge current, -40°C to 70°C, 20-HTSSOP.","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":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant","Base Product Number":"BQ24002","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.2A","Operating Temperature":"-40°C~70°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"10V","Supplier Device Package":"20-HTSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$50.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6312853505ca2072a37f28e7f44f90ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24002PWPG4/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24002PWPG4 obsolete or end of life?","answer":"No. The manufacturer lists the product status as active."},{"question":"What is the maximum charge current for BQ24002PWPG4?","answer":"The maximum charge current is 1.2 A.

The key difference is the maximum charge current: the BQ24002PWPG4 is rated for 1.2 A, while the BQ24003 is typically rated for a lower current (check the BQ24003 datasheet for the exact value). If your design needs the full 1.2 A, the BQ24002PWPG4 is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ24002PWPG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ24002PWPG4 when reusing this data.
