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. ## Sourcing and lifecycle posture 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/033374a2dfc4db735f78429d1a9e7208.pdf","sourceUrl":null},"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.
