It delivers a programmable constant charge current up to 500 mA maximum, with a fixed battery regulation voltage of 4.2 V. The IC integrates fault protection for over-temperature conditions and offers programmable charge current and charge-timer features. ## Charge current and timer programming — setting the charge profile The charge current is constant and programmable via an external resistor, with a maximum of 500 mA. The safety timer is also programmable, allowing the designer to set a maximum charge duration that matches the battery capacity and C-rate. These two programmable features — current and timer — are the main configuration knobs for the charge profile; no I²C or SMBus interface is used. For a typical 500 mAh to 2000 mAh single-cell Li-Ion pack, the 500 mA ceiling means a charge current of 0.25C to 1C, which is within the standard charge-rate window for most consumer cells. The timer should be set to accommodate the full CC-CV cycle; a common starting point is 3 to 6 hours depending on the cell's charge acceptance at the C-rate. ## Package and thermal management — 10-VSON with exposed pad The BQ24027DRCT is supplied in a 10-pin VFDFN with an exposed pad (3 mm × 3 mm VSON package). Surface-mount assembly per standard MSL ratings applies; the package is RoHS-compliant and shipped in Tape & Reel (TR) format. ## Lifecycle status — obsolete, sourced via independent distribution The BQ24027DRCT is listed as obsolete by the manufacturer.","metaTitle":"BQ24027DRCT bqTINY-II Li-Ion Charger, 500 mA, USB, Obsolete","metaDescription":"Texas Instruments BQ24027DRCT single-cell Li-Ion/Polymer linear charger, USB interface, 500 mA max charge current, -40°C to 125°C junction range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™-II","Package":"Tape & Reel (TR)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Obsolete","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24027","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"10-VSON (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5231bfebd8a96493d69d3ffb619779e5.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can I use BQ24027DRCT with a single 4.2V Li-Po cell?","answer":"Yes, the BQ24027DRCT is designed specifically for single-cell Lithium Ion/Polymer batteries with a regulation voltage of 4.2 V.
