The 10-WSON package (3x2 mm) with exposed pad keeps junction temperature under control even at the full 800 mA charge rate, so you skip the external heatsink and keep the board layout tight. Input supply maxes at 18 V, which covers 5 V USB, 9 V wall adapters, and 12 V rails without a front-end regulator. ## Programmable charge current — set it with one resistor The charge current is constant and programmable via a single external resistor. At the 800 mA maximum, the thermal dissipation in the WSON pad is manageable with proper PCB copper area — a 2-layer board with a 1-inch-square ground plane under the pad keeps the die below the thermal regulation threshold during a full charge cycle. ## On-chip fault protection covers the common failure modes Over-temperature, over-voltage, and short-circuit protection are integrated, so a single-chip charge controller handles the safety interlocks without external comparators or supervisory ICs. The thermal regulation loop reduces charge current if the die temperature climbs above the internal limit, which matters when the ambient hits 85°C and the charger is running at full rate.","metaTitle":"BQ24210DQCT Li-Ion Charger IC, 800mA Max, Active","metaDescription":"TI BQ24210DQCT single-cell Li-Ion charger, 800mA max charge current, 4.2V termination, -40°C to 85°C, 10-WSON 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); Cut Tape (CT)","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24210","Battery Pack Voltage":"4.2V","Charge Current - Max":"800mA","Operating Temperature":"-40°C~85°C(TA)","Programmable Features":"-","Voltage - Supply (Max)":"18V","Supplier Device Package":"10-WSON (3x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.4200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/91ec31c95997b2a5f61f6aa256cfabfb.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24210DQCT?","answer":"The maximum programmable charge current is 800 mA.
