It delivers a programmable charge current up to 1.5 A from a USB or wall-adapter input rated to 16 V maximum, which gives headroom for 5 V or 9 V adapters without an external clamp. ## Programmable current and timer with built-in fault monitoring Charge current and safety timer are programmable via external resistors, giving the designer control over the charge profile without firmware. The IC integrates over-temperature, reverse-current, and short-circuit protection, so a single fault event won't cascade into a battery or system failure.","metaTitle":"BQ24031RHLT – Texas Instruments Li-Ion Charger IC, 1.5 A","metaDescription":"Texas Instruments BQ24031RHLT single-cell Li-Ion/Polymer charger IC from the bqTINY™ III series. 1.5 A max charge current, 16 V input, -40°C to 125°C range.","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":"BQ24031","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/BQ24031RHLT/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24031RHLT a direct replacement for BQ24030?","answer":"The BQ24031RHLT and BQ24030 share the same base product family (BQ2403x) and are both single-cell Li-Ion chargers in the bqTINY™ III series. The key difference is the battery pack voltage: the BQ24031RHLT regulates to 4.36 V, while the BQ24030 regulates to 4.2 V.
