The linear regulation topology means all voltage drop between the input supply and the battery is dissipated as heat in the pass element. The programmable current feature lets you dial back the charge rate if the board's thermal budget cannot handle the full 1.2 A. ## Supply voltage and input protection The maximum supply voltage is 10 V, which covers standard 5 V USB and 9 V wall-adapter inputs but excludes 12 V or higher rails. The charger includes over-temperature fault protection that shuts down the pass element if the die temperature exceeds the thermal limit — a necessary safeguard given the dissipation at high charge currents. There is no battery thermistor input on this variant; the safety timer (programmable via an external capacitor) provides the backup termination if the battery never reaches the 4.2 V regulation voltage. ## Operating range and deployment environments The temperature floor allows cold-start charging down to -40°C, though charge current should be reduced below 0°C per the battery manufacturer's guidelines. The 70°C ceiling limits deployment in engine bays, solar-exposed outdoor enclosures, or other high-ambient environments.","metaTitle":"BQ24002PWPRG4 Texas Instruments Li-Ion Charger IC, 1.2 A","metaDescription":"TI BQ24002PWPRG4 single-cell Li-Ion linear charger IC, 4.2 V, 1.2 A max, 20-PowerTSSOP, active.","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":"20-PowerTSSOP (0.173\\\", 4.40mm Width)","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant","Base Product Number":"BQ24002","Battery Pack Voltage":"4.2V","Charge Current - Max":"1.2A","Operating Temperature":"-40°C~70°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"10V","Supplier Device Package":"20-HTSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$50.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6312853505ca2072a37f28e7f44f90ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24002PWPRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24002PWPRG4?","answer":"The maximum charge current is 1.2 A, delivered as a constant-current charge to the single-cell Li-Ion battery.
