It accepts a supply input up to 34V, which gives headroom for 24V industrial rails or automotive systems with load-dump transients. The charge current is programmable up to 2A, and a timer termination option is built in — no external microcontroller needed for basic charge management. The operating junction temperature range of -40°C to 125°C suits it for outdoor telecom enclosures, engine-bay-adjacent electronics, or factory-floor charger modules where ambient heat is a given. ## Charge profile and chemistry flexibility Multi-chemistry support means this IC can handle Li-Ion, LiFePO4, or lead-acid chemistries with appropriate resistor divider settings on the output voltage feedback. The constant-current, constant-voltage (CC/CV) profile is standard for Li-Ion; the programmable timer provides a safety backup if the termination current threshold is not reached. The 2A maximum charge current suits 4S or 5S packs. ## Package and mounting — what the 12-TSSOP exposed pad means for your board The package with exposed pad (3.00 mm width) is a surface-mount design. The exposed pad must be soldered to a thermal land on the PCB — it is the primary heat path for the 2A charge current. ## Lifecycle — active, no LTB watch needed The LT3652HVEMSE#PBF carries an Active lifecycle status. There is no last-time-buy window, no NRND flag, and no announced end-of-life. For a BOM freeze or a new-design qualification, this part does not introduce obsolescence risk. The ROHS3 compliance is confirmed.","metaTitle":"LT3652HVEMSE#PBF Multi-Chemistry Battery Charger IC","metaDescription":"LT3652HVEMSE#PBF is an active multi-chemistry battery charger IC from Analog Devices.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"12-TSSOP (0.118\\\", 3.00mm Width) Exposed Pad","Number of Cells":"4 ~ 5","lifecycle_stage":"eol_hot","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"18V (Max)","Charge Current - Max":"2A","Operating Temperature":"-40°C ~ 125°C (TJ)","Programmable Features":"Current, Timer","Voltage - Supply (Max)":"34V","Supplier Device Package":"12-MSOP-EP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.81000","currency":"USD"},{"qty":10,"price":"$8.86000","currency":"USD"},{"qty":25,"price":"$8.44760","currency":"USD"},{"qty":100,"price":"$7.33500","currency":"USD"},{"qty":250,"price":"$7.00536","currency":"USD"},{"qty":500,"price":"$6.38724","currency":"USD"},{"qty":1000,"price":"$5.56308","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/785954794f711d4d921a97927a296944.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LT3652HVEMSE#PBF equivalent to LT3652HVEMSE?","answer":"The LT3652HVEMSE#PBF and LT3652HVEMSE share the same base part number and functional specifications — both are multi-chemistry chargers with 34V input, 18V pack voltage, and 2A charge current. The #PBF suffix indicates ROHS3 compliance (lead-free). The two are electrically equivalent; the #PBF variant is the current ROHS-compliant ordering code."},{"question":"What are the alternatives to LT3652HVEMSE#PBF?","answer":"Within the same LT3652 family, the LT3652HVIMSE#PBF is the closest functional peer — same package, same 4-5 cell support, same 125°C temperature rating, and same programmable features. The LT3652IMSE#PBF and LT3652EDD#PBF are lower-voltage variants (14.4V pack max) for 2-3 cell applications. None are pin-compatible substitutes without checking the feedback divider network."},{"question":"What is the LT3652HVEMSE#PBF datasheet and pinout?","answer":"The full datasheet is available from Analog Devices. The pinout follows the standard 12-lead MSOP-EP / TSSOP-EP arrangement: the exposed pad is the thermal and ground connection. For detailed pin assignments, refer to the manufacturer's datasheet — the pin functions are consistent across the LT3652 family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT3652HVEMSEPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT3652HVEMSEPBF when reusing this data.
