It accepts power from a USB port or a DC adapter up to 16V and delivers a programmable constant charge current with a 1.5A maximum ceiling. The device integrates over-temperature, reverse-current, and short-circuit fault protection, and includes programmable current and timer features for charge management. ## Charge current programming and thermal envelope The charge current is constant and programmable via an external resistor (ISET pin), allowing the designer to set the rate anywhere below the 1.5A maximum. The BQ24032RHLRG4 carries an Obsolete product status per the manufacturer.","metaTitle":"BQ24032RHLRG4 Li-Ion Charger IC, 1.5A, bqTINY III, Obsolete","metaDescription":"Texas Instruments BQ24032RHLRG4 single-cell Li-Ion/Polymer charger IC. 1.5A max charge current, USB interface, 16V input.","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™ III","Package":"Tape & Reel (TR)","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Obsolete","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":"BQ24032","Battery Pack Voltage":"4.2V","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":"$58.8000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/155f0f0ab4405e3bb05102da094504d1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BQ24032RHLRG4?","answer":"No official replacement or successor order code is recorded for this part. For a pin-compatible alternative within the bqTINY III family, review the BQ24032RHLR variant — the difference is the package tape-and-reel suffix. Confirm the pinout and charge parameters against your BOM before substituting."},{"question":"What is the charging current of BQ24032RHLRG4?","answer":"The maximum charge current is 1.5A. The current is constant and programmable via an external resistor, so the actual charge rate is set below that ceiling by the designer."},{"question":"What is the difference between BQ24032RHLRG4 and BQ24032RHLR?","answer":"The base product number is BQ24032 for both.
