It charges a 3.95V battery pack at up to 1.5A, with the charge current set by an external resistor — no firmware handshake needed for the constant-current phase. The 5.5V max supply voltage covers standard USB bus power (5V nominal) with margin for cable drop and connector resistance. The part operates across the full -40°C to 85°C industrial temperature range, so it suits outdoor handhelds or gear that sees a hot dashboard in summer. ## 14-DFN package and board-level fit Housed in a 14-lead WFDFN with exposed pad (4x3 mm body), the LTC4085EDE-4#PBF uses the pad as the primary thermal path. The PCB layout needs a thermal via array under the pad to pull heat into the ground plane — without it the 1.5A charge current pushes the die temperature above the 85°C ambient ceiling on a two-layer board. The surface-mount DFN footprint is common for portable designs; the 0.5 mm pitch and exposed pad are standard for reflow assembly. No special stencil aperture beyond the usual 50-60% paste coverage on the pad. ## Sourcing and compliance status Marked as Active by Analog Devices with RoHS3 compliance.","metaTitle":"LTC4085EDE-4#PBF Analog Devices Li-Ion Charger, 1.5A, 14-DFN","metaDescription":"Active LTC4085EDE-4#PBF Li-Ion/Polymer charger IC from Analog Devices. 1.5A max charge current, 3.95V battery pack voltage, USB interface, 14-DFN package.","metaKeywords":null},"attributes":{"series":"PowerPath™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"PowerPath™","Package":"Tube","Interface":"USB","Mounting Type":"Surface Mount","Package / Case":"14-WFDFN Exposed Pad","Number of Cells":"1","lifecycle_stage":"eol_hot","Battery Chemistry":"Lithium Ion/Polymer","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"3.95V","Charge Current - Max":"1.5A","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Supply (Max)":"5.5V","Supplier Device Package":"14-DFN (4x3)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.90000","currency":"USD"},{"qty":10,"price":"$4.39900","currency":"USD"},{"qty":91,"price":"$3.60418","currency":"USD"},{"qty":273,"price":"$3.41934","currency":"USD"},{"qty":546,"price":"$3.06819","currency":"USD"},{"qty":1001,"price":"$2.58762","currency":"USD"},{"qty":2548,"price":"$2.45824","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"How can I order LTC4085EDE-4#PBF or check availability?","answer":"The LTC4085EDE-4#PBF is an active part from Analog Devices.
