It delivers a programmable constant charge current up to 2A from a supply rail rated to 16V. ## Charge current and programmable features Maximum charge current is 2A, set via an external resistor. The charger supports constant-current/constant-voltage (CC/CV) profiles and includes programmable charge current and timer features — the timer provides a safety termination if the battery does not reach full voltage within the set window. Fault protection includes over-temperature and over-voltage monitoring, reducing the need for external supervisory ICs. The BQ24115RHLRG4 is listed as obsolete by Texas Instruments. No official replacement part number is recorded in the lifecycle data.","metaTitle":"BQ24115RHLRG4 bqSWITCHER Li-Ion Charger, 2A, 16V, Obsolete","metaDescription":"Texas Instruments BQ24115RHLRG4 multi-chemistry battery charger, 2A max charge current, 16V input, -40°C to 85°C, 20-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqSWITCHER™","Package":"Tape & Reel (TR)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"1 ~ 3","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24115","Battery Pack Voltage":"15.5V","Charge Current - Max":"2A","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$118.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26d08c6a9886ba7ed4911c20d19d787e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BQ24115RHLRG4?","answer":"No official replacement part number is listed in the lifecycle data. For a drop-in alternative, review the bqSWITCHER family for a currently active charger with similar 2A maximum charge current, 16V input rating, and 1-3 cell support. The BQ24115RHLRG4 uses a 20-VQFN (3.5x4.5) package — any replacement must match the footprint and thermal pad layout."},{"question":"Can BQ24115RHLRG4 charge Li-ion batteries?","answer":"Yes, the BQ24115RHLRG4 supports multi-chemistry batteries including Li-ion.
