The 5 A max charge current and 18.8 V max battery pack voltage define the charge-time floor and the cell-count ceiling for a portable or battery-backup design. The 24 V supply maximum gives headroom for USB-C PD or a 19 V adapter without a separate pre-regulator. ## Fault protection set — what it covers The charger integrates over-current, over-temperature, over-voltage, reverse battery, and short-circuit protection. That coverage means the external supervisory circuit can be pared back — the part itself handles the common failure modes a Li-ion pack can present during charging or a reverse-plug event. ## Package and layout — 56-DSBGA 2.9x3.32 mm The 56-DSBGA (2.9x3.32 mm) package is a 0.4 mm pitch BGA. The small footprint suits space-constrained portable products, but the fine pitch demands a controlled-impedance PCB stack-up and a via-in-pad process for the centre thermal pad.","metaTitle":"BQ25790YBGR I²C Buck-Boost Charger, 5 A, 1–4 Cells","metaDescription":"TI BQ25790YBGR I²C-controlled buck-boost Li-ion charger, 5 A max charge current, 1–4 cells, 24 V input.","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":"I²C","Mounting Type":"Surface Mount","Package / Case":"56-XFBGA, DSBGA","Product Status":"Active","Number of Cells":"1 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Temperature, Over Voltage, Reverse Battery, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant","Base Product Number":"BQ25790","Battery Pack Voltage":"18.8V (Max)","Charge Current - Max":"5A","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Current, Timer, Voltage","Voltage - Supply (Max)":"24V","Supplier Device Package":"56-DSBGA (2.9x3.32)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0762","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/99081f631ad1b0dede815556ec5d64a0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many battery cells does the BQ25790YBGR support?","answer":"The BQ25790YBGR supports 1 to 4 series Li-ion or Li-polymer cells, with a maximum battery pack voltage of 18.8 V."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/BQ25790YBGR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/BQ25790YBGR when reusing this data.
