It delivers a programmable charge current up to 2A, with a termination voltage of 4.2V — the standard float voltage for these chemistries. The input supply can range up to 16V, making it compatible with common 5V USB adapters or 12V wall warts without an external pre-regulator. ## Industrial temperature range and fault protection On-chip fault protection covers over-temperature and over-voltage conditions — the charger shuts down before the battery or the IC itself is stressed beyond safe limits. ## Package and programming options Housed in a 20-VFQFN with exposed pad (3.5x4.5 mm body), the part requires a thermal land pattern on the PCB to pull heat from the die. The charge current and safety timer are programmable via external resistors — no I²C or SMBus interface needed, which simplifies the BOM for a standalone charger block.","metaTitle":"BQ24109RHLR Li-Ion/Polymer Charger IC, 2A Max, 20-VQFN","metaDescription":"Texas Instruments BQ24109RHLR single-cell Li-Ion/Polymer charger IC with 2A max charge current, 16V input, -40°C to 85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqSWITCHER™","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24109","Battery Pack Voltage":"4.2V","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":"$2.9100","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26d08c6a9886ba7ed4911c20d19d787e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24109RHLR?","answer":"The maximum charge current is 2A, programmable via an external resistor.
