It accepts a USB or unregulated DC input up to 28 V and delivers a programmable constant charge current up to 800 mA. The device integrates over-temperature, over-voltage, and short-circuit fault protection, reducing external component count. The charge current is set via an external resistor — no I2C or GPIO needed. ## Charge current and input voltage headroom Maximum charge current of 800 mA suits single-cell packs up to 4.2 V termination. The 28 V input ceiling covers unregulated wall adapters and USB-C PD sources; a 6.5 V input clamp protects the IC during hot-plug transients. The 10-WSON (2x2) package with exposed pad keeps thermal resistance low — important for linear charging at 800 mA when input-to-battery differential exceeds 1 V. This part is suitable for both prototyping and volume production without supply-chain disruption.","metaTitle":"TI BQ24052DSQR Li-Ion Charger IC, 800 mA, 28 V Input","metaDescription":"Texas Instruments BQ24052DSQR single-cell Li-Ion/Polymer charger IC. 800 mA max charge current, 28 V input, over-voltage/short-circuit protection.","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)","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":"$0.8115","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9d456077ff50bae65c6ef17642eed549.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the BQ24052DSQR maximum charge current?","answer":"The maximum charge current is 800 mA, programmable via an external resistor.
