It integrates over-current, over-voltage, and short-circuit protection, reducing external monitoring circuitry. The part targets portable electronics, notebooks, and industrial handhelds where the host microcontroller manages the charge profile via the SMBus/I²C interface. The pad needs a via array to the ground plane for thermal relief — without it, the junction temperature climbs fast at higher charge currents. Clean the pad, apply fresh solder paste, and reflow. The orientation mark is at pin 1 (A1 corner), visible under magnification. ## Supply voltage and cell-count flexibility The charger accepts a maximum supply of 24 V and handles battery packs up to 19.2 V, covering 1S through 4S Li-Ion configurations.","metaTitle":"BQ24725ARGRR Li-Ion Battery Charger IC, 1-4 Cells, I²C","metaDescription":"TI BQ24725ARGRR is an active Li-Ion battery charger IC for 1-4 cells, I²C programmable, 19.2V max pack voltage, 24V supply max, 20-VQFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Interface":"I²C","Mounting Type":"Surface Mount","Package / Case":"20-VFQFN Exposed Pad","Product Status":"Active","Number of Cells":"1 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Current, Over Voltage, Short Circuit","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Base Product Number":"BQ24725","Battery Pack Voltage":"19.2V (Max)","Charge Current - Max":"-","Operating Temperature":"0°C~125°C(TJ)","Programmable Features":"-","Voltage - Supply (Max)":"24V","Supplier Device Package":"20-VQFN (3.5x3.5)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.4200","priceTiers":[{"qty":1,"price":"$4.42000","currency":"USD"},{"qty":10,"price":"$3.97300","currency":"USD"},{"qty":25,"price":"$3.75640","currency":"USD"},{"qty":100,"price":"$3.25550","currency":"USD"},{"qty":250,"price":"$3.08856","currency":"USD"},{"qty":500,"price":"$2.77136","currency":"USD"},{"qty":1000,"price":"$2.36250","currency":"USD"},{"qty":3000,"price":"$2.36250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6e9928f499daf85193de8c8ff5ba3bbf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BQ24725ARGRR/alternatives.json"},"ai":{"faq":[{"question":"Is BQ24725ARGRR compatible with 3-cell lithium batteries?","answer":"Yes.
