That 28V ceiling covers common adapter rails like 19V laptops and 24V industrial supplies without needing a pre-regulator — but you lose headroom if the adapter can spike above 28V during hot-plug or load dump. It supports multi-chemistry charging, which means one BOM line can handle Li-ion, Li-Polymer, and NiMH packs by swapping the charge algorithm in firmware — useful for a product line that ships with different battery types. The 85°C ceiling is the ambient limit, not the junction — the TSSOP's thermal pad (if present) and board copper area set the real thermal budget at full charge current. The BQ24702 base number shares the same pinout across the family, so if TI ever phases out the PWRG4 tape-and-reel variant, the tube-packaged BQ24702PW would be the drop-in replacement without a board spin.","metaTitle":"BQ24702PWRG4 Battery Charger IC, 28V Input, Multi-Chemistry","metaDescription":"Texas Instruments BQ24702PWRG4 multi-chemistry battery charger IC. 28V max supply, -40°C to 85°C operating range, 24-TSSOP 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)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"24-TSSOP (0.173\\\", 4.40mm Width)","Number of Cells":"-","lifecycle_stage":"eol_hot","Fault Protection":"-","Battery Chemistry":"Multi-Chemistry","Current - Charging":"-","Base Product Number":"BQ24702","Battery Pack Voltage":"-","Charge Current - Max":"-","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"28V","Supplier Device Package":"24-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/033374a2dfc4db735f78429d1a9e7208.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24702PWRG4/alternatives.json"},"ai":{"faq":[{"question":"What battery chemistries does BQ24702PWRG4 support?","answer":"It is rated for multi-chemistry charging, covering Li-ion, Li-Polymer, and NiMH cells.
