Charge current is constant and programmable, with a maximum of 800 mA. The 12-WSON (2x3) package with exposed pad suits space-constrained portable designs. For BOM lines still requiring this exact order code, we source through our independent supply network. ## Fault protection and temperature range On-chip fault protection covers over-temperature, over-voltage, and short-circuit conditions. The junction temperature range spans 0°C to 125°C, covering commercial and some industrial ambient environments.","metaTitle":"BQ24055DSSR Texas Instruments Li-Ion Charger – Obsolete","metaDescription":"BQ24055DSSR is an obsolete single-cell Li-Ion charger from TI. 800 mA max charge current, USB interface, 28 V input.","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":"USB","Mounting Type":"Surface Mount","Package / Case":"12-WFDFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24055","Battery Pack Voltage":"4.2V","Charge Current - Max":"800mA","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"Current","Voltage - Supply (Max)":"28V","Supplier Device Package":"12-WSON (2x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9d456077ff50bae65c6ef17642eed549.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the BQ24055DSSR obsolete, and what is its lifecycle status?","answer":"No direct replacement or successor MPN has been published by TI."},{"question":"What is the closest alternative to the BQ24055DSSR in the TI charger family?","answer":"No pin-compatible replacement is formally documented by Texas Instruments.
