It accepts a supply up to 16V and delivers a programmable constant-current charge up to 1.5A, with a battery regulation voltage of 4.36V. The charger integrates fault protection against over-temperature, reverse current, and short circuits, and includes programmable charge-current and timer features. With a 16V maximum input rating, the BQ24038RHLT can tolerate 5V USB bus voltage with margin for cable drop and transients, and can also run from unregulated wall adapters up to 16V. The 1.5A maximum charge current allows fast charging of a typical 1000–2000 mAh single-cell pack, but the actual current is set by the external programming resistor – so you trade charge time against thermal dissipation in the linear pass element. Because this is a linear charger, the power dissipated equals (VIN – VBAT) × ICHG. The datasheet layout recommendation for the pad is critical; skipping it derates the usable charge current. We source directly from TI-authorized channels; no spot-market risk. For volume requirements, request a quote – lead times are typical for active TI power-management ICs.","metaTitle":"BQ24038RHLT Li-Ion Battery Charger IC – Texas Instruments","metaDescription":"BQ24038RHLT from Texas Instruments: single-cell Li-Ion/Polymer charger, 16V max input, 1.5A charge current, 20-VFQFN package.","metaKeywords":null},"attributes":{"series":"bqTINY™ III","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"bqTINY™ III","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature, Reverse Current, Short Circuit","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24038","Battery Pack Voltage":"4.36V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C~125°C(TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"16V","Supplier Device Package":"20-VQFN (3.5x4.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.6100","priceTiers":[{"qty":1,"price":"$5.61000","currency":"USD"},{"qty":10,"price":"$5.03600","currency":"USD"},{"qty":25,"price":"$4.76040","currency":"USD"},{"qty":100,"price":"$4.12570","currency":"USD"},{"qty":250,"price":"$3.91416","currency":"USD"},{"qty":500,"price":"$3.51216","currency":"USD"},{"qty":1250,"price":"$2.99400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ac9036052305c74527f033a709990eb1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24038RHLT/alternatives.json"},"ai":{"faq":[{"question":"Can the BQ24038RHLT charge Lithium Polymer batteries?","answer":"Yes, the device is specified for both Lithium-Ion and Lithium-Polymer chemistries, with a single-cell battery pack voltage of 4.36V."},{"question":"Is the BQ24038RHLT a linear or switching charger?","answer":"It is a linear (constant-current / constant-voltage) charger.
