It delivers a programmable constant charge current up to 450mA to a 4.2V battery pack, with over-temperature protection and a programmable timer for charge termination. This part is aimed at portable and handheld devices where board space is tight and a simple, integrated charge solution is needed — think Bluetooth headsets, wearable sensors, or small IoT peripherals that run on a single Li-ion cell. ## Key ratings and what they mean for the BOM The 450mA maximum charge current sets the charge rate for a 1-cell Li-Ion pack. For a typical 500 mAh cell, that works out to roughly a 0.9C rate — a full charge in about an hour and a half, assuming the input supply can deliver the current. The 4.2V battery pack voltage is the standard termination voltage for Li-Ion and Li-Polymer cells, so no special cell matching is needed. Over-temperature protection is a hard shutdown on the die temperature — it keeps the part from running away if the board is in a warm enclosure or the charge current is sustained near the limit. The programmable timer lets you set a safety timeout, which is useful if the cell is deeply discharged or damaged and never reaches the voltage threshold. The supply voltage range goes up to 6.5V, which covers USB (5V nominal) and most wall-wart inputs. The operating temperature range of -20°C to 70°C is typical for consumer and commercial portable gear — not rated for automotive under-hood or industrial oven environments, but fine for indoor and outdoor handheld use down to freezing. The 10-DFN (3x3 mm) package with exposed pad requires a thermal via under the pad to the ground plane; without it, the junction temperature climbs quickly at 450mA continuous charge. ## Lifecycle and sourcing reality The ISL6298-2CR3Z is listed as Active and ROHS3 Compliant. For a BOM line, this part carries no immediate obsolescence risk.","metaTitle":"ISL6298-2CR3Z Li-Ion Battery Charger IC, 1-Cell, 450mA","metaDescription":"ISL6298-2CR3Z is a 1-cell Li-Ion/Polymer battery charger IC with 450mA max charge current, over-temperature protection, and timer programmability.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Fault Protection":"Over Temperature","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"4.2V","Charge Current - Max":"450mA","Operating Temperature":"-20°C ~ 70°C (TA)","Programmable Features":"Timer","Voltage - Supply (Max)":"6.5V","Supplier Device Package":"10-DFN (3x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.17","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.17000","currency":"USD"},{"qty":10,"price":"$2.85100","currency":"USD"},{"qty":25,"price":"$2.69520","currency":"USD"},{"qty":100,"price":"$2.33570","currency":"USD"},{"qty":250,"price":"$2.21592","currency":"USD"},{"qty":500,"price":"$1.98834","currency":"USD"},{"qty":1000,"price":"$1.88710","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3dc1dcfeb915117295411b96ab77ed8d.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/renesas/ISL6298-2CR3Z","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/renesas/ISL6298-2CR3Z when reusing this data.
