It integrates short-circuit fault protection and offers programmable charge current and charge-timer features, making it suitable for low-capacity coin-cell or small-format Li-ion applications where the charge rate stays under 30 mA. The 30 mA charge-current ceiling sets the practical battery capacity this part can handle — a 100 mAh cell charges at roughly C/3, a 200 mAh cell at C/6.7, so the charge time scales inversely with the current limit. Operating temperature spans -20°C to 85°C, which covers most portable and industrial indoor environments but not extended automotive or high-temp enclosure duty.","metaTitle":"BQ24901PW Texas Instruments Li-Ion Charger, 30mA, 14-TSSOP","metaDescription":"Texas Instruments BQ24901PW single-cell Li-Ion/Polymer linear charger. 30mA max charge current, 4.2V pack voltage, short-circuit protection.","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":"$4.2000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f10b8961fefd53bde0de28de34b2f427.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24901PW/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum charge current for BQ24901PW?","answer":"The maximum charge current is 30 mA, programmable via an external resistor.
