It charges a 4.2V battery pack at a programmable constant current up to 800mA, which means a typical 1000mAh cell can be charged in roughly 1.5 hours if the input supply can deliver the current. The USB interface simplifies connection to a standard USB port or a dedicated charger adapter — the IC handles the negotiation and current limiting internally. ## Fault protection and temperature range Built-in fault protection covers over-temperature, over-voltage, and short-circuit conditions — the IC shuts down or limits the charge cycle automatically, reducing the risk of battery damage or thermal runaway in a portable device. The junction temperature range is rated from 0°C to 125°C, which allows operation in warm enclosures or near a power-hungry processor without derating the charge current. ## Package and footprint for compact designs Housed in a 10-WFDFN with exposed pad, the supplier device package is 10-WSON measuring 2x2 mm — the small footprint and low profile suit space-constrained wearable or IoT designs. ## Sourcing and lifecycle posture Cut tape (CT) is also available for prototype builds.","metaTitle":"BQ24052DSQT Li-Ion Charger IC – 28V Input, 800mA, USB","metaDescription":"Texas Instruments BQ24052DSQT single-cell Li-Ion/Polymer charger IC. 28V max input, 800mA programmable charge current, USB interface, 10-WSON package.","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); Cut Tape (CT)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","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":"BQ24052","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":"10-WSON (2x2)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/00cba9679cda08bcb6988b327ded92d0.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BQ24052DSQT compatible with 4.2V Li-ion batteries?","answer":"Yes — the battery pack voltage is fixed at 4.2V, which is the standard termination voltage for single-cell Li-ion and Li-Polymer cells.
