Its max charge current is 30 mA — that puts it firmly in trickle-charge territory, sized for small coin cells or very low-capacity Li-Po pouches (under 100 mAh). It is not a candidate for phone, tablet, or power-tool battery charging, where 1 A+ rates are standard. The battery termination voltage is fixed at 4.2 V, the standard for single-cell Li-Ion/Polymer. Input supply can go up to 10 V. The device includes short-circuit fault protection and programmable charge current and timer via external components. ## Package and mounting The BQ24901PWG4 comes in a 14-TSSOP package, 0.173-inch body width, 4.40 mm wide. It will survive a hot-air rework cycle if you preheat the board to 100 °C and keep the nozzle off the plastic. Mounting is surface-mount; the shipping medium is tube, not tape-and-reel, so factor that into pick-and-place setup if you are running a small batch. ## Obsolete — sourcing reality The BQ24901PWG4 carries an Obsolete lifecycle status. No stock-holding claim is made here.","metaTitle":"BQ24901PWG4 Li-Ion/Polymer Charger IC, 30 mA Max, 14-TSSOP","metaDescription":"Texas Instruments BQ24901PWG4 single-cell Li-Ion/Polymer linear charger IC. 30 mA max charge current, 4.2 V battery voltage, 14-TSSOP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tube","Interface":"-","Mounting Type":"Surface Mount","Package / Case":"14-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24901","Battery Pack Voltage":"4.2V","Charge Current - Max":"30mA","Operating Temperature":"-20°C~85°C(TA)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"10V","Supplier Device Package":"14-TSSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f10b8961fefd53bde0de28de34b2f427.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy BQ24901PWG4 available via RFQ confirmation?","answer":"The BQ24901PWG4 is obsolete and not available through normal factory distribution."},{"question":"What is the charge current of BQ24901PWG4?","answer":"The maximum charge current is 30 mA, programmable via an external resistor.
