The charge voltage is fixed at 4.2V, matching the standard termination voltage for a single Li-Ion/Polymer cell. The IC integrates short-circuit protection and supports programmable charge current and timer via external components. ## Obsolete — sourcing through independent distribution The BQ24901PWR carries an Obsolete product status per the manufacturer. Availability is limited to surplus and broker-channel inventory. ## 14-TSSOP footprint and surface-mount assembly The 0.65 mm pin pitch is standard for this package family and routes cleanly on a two-layer board with a solid ground plane under the charger section. Operating temperature range is -20°C to 85°C, suitable for consumer and industrial environments where the charger is not exposed to extreme cold or under-hood heat.","metaTitle":"BQ24901PWR Li-Ion/Polymer Charger IC, 30 mA Max, 14-TSSOP","metaDescription":"Texas Instruments BQ24901PWR single-cell Li-Ion/Polymer charger IC, 30 mA max charge current, 4.2V pack voltage, 14-TSSOP.","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":"Tape & Reel (TR)","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","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f10b8961fefd53bde0de28de34b2f427.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BQ24901PWR?","answer":"No official replacement or successor part number is recorded for the BQ24901PWR.
