The 4.2V battery pack voltage is the standard termination for a single Li-Ion or Li-Polymer cell; the charger enters constant-voltage regulation at that threshold, so the downstream load must tolerate the full 4.2V rail without overvoltage damage. The programmable constant-current feature lets the host choose a lower charge rate via I²C, which matters when the input supply is limited or when charging at reduced current extends cell cycle life. The over-temperature protection shuts down the charger if the die exceeds the safe threshold, which protects both the IC and the battery during a fault — a useful safeguard when the device is in an unventilated enclosure or near a heat source.","metaTitle":"TPS65010RGZRG4 Li-Ion Charger IC, 4.2V, 500mA, I²C/USB","metaDescription":"Texas Instruments TPS65010RGZRG4 single-cell Li-Ion/Polymer charger IC. 4.2V battery pack voltage, 500mA max charge current, I²C and USB interface.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Interface":"I²C, USB","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN 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":"TPS65010","Battery Pack Voltage":"4.2V","Charge Current - Max":"500mA","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"-","Voltage - Supply (Max)":"5.5V","Supplier Device Package":"48-VQFN (7x7)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.4100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/edba2f906d2fe026ccaa7590407e26b9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65010RGZRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS65010RGZRG4 and TPS65010RGZR?","answer":"The RGZR suffix typically indicates a different packaging option or reel configuration, but the base product number TPS65010 is shared. The RGZRG4 variant is the Tape & Reel (TR) packaged version. The functional specifications — single-cell Li-Ion/Polymer charger at 4.2V with 500 mA max charge current, I²C and USB interface — are identical across the TPS65010 family. Confirm the exact suffix against your BOM's packing requirement before ordering."},{"question":"Can TPS65010RGZRG4 be used with 4.2V batteries?","answer":"Yes, the TPS65010RGZRG4 is designed for a 4.2V battery pack voltage, which is the standard termination voltage for a single-cell Li-Ion or Li-Polymer cell. The charger regulates at that threshold during the constant-voltage phase."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65010RGZRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65010RGZRG4 when reusing this data.
