It accepts a supply voltage up to 28V, making it suitable for industrial and automotive battery management systems where the input rail can vary widely. The part integrates over-voltage fault protection and operates across the full -40°C to 125°C temperature range, so it can sit in an engine bay or a factory-floor charger without derating concerns. The 20-QFN (4x4) package keeps the footprint small for space-constrained power stages. ## Multi-chemistry charging: one BOM for multiple battery types Because the LTC4012IUF#PBF supports multi-chemistry charging, a single board can handle Li-Ion, LiFePO4, NiMH, or lead-acid packs by changing the charge termination algorithm in the external controller. That saves a board spin when a customer switches battery chemistries mid-production. The constant programmable current lets you set the charge rate with a single resistor — no firmware dependency for the current limit. ## Temperature grade and environment Rated for -40°C to 125°C, this IC qualifies for under-hood automotive, outdoor telecom cabinets, and high-ambient industrial enclosures where forced cooling isn't available. The 20-QFN package with exposed pad helps pull heat into the PCB copper plane — make sure the thermal vias are sized for the charge current you plan to run.","metaTitle":"LTC4012IUF#PBF Multi-Chemistry Battery Charger IC, 28V","metaDescription":"LTC4012IUF#PBF from Analog Devices (PowerPath series) is a multi-chemistry battery charger IC supporting 1-4 cells, 28V max supply, constant programmable","metaKeywords":null},"attributes":{"series":"PowerPath™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Series":"PowerPath™","Package":"Tube","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN Exposed Pad","Number of Cells":"1 ~ 4","lifecycle_stage":"eol_hot","Fault Protection":"Over Voltage","Battery Chemistry":"Multi-Chemistry","Current - Charging":"Constant - Programmable","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Supply (Max)":"28V","Supplier Device Package":"20-QFN (4x4)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.94","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.94000","currency":"USD"},{"qty":10,"price":"$9.88000","currency":"USD"},{"qty":25,"price":"$9.42080","currency":"USD"},{"qty":100,"price":"$8.18000","currency":"USD"},{"qty":250,"price":"$7.81236","currency":"USD"},{"qty":500,"price":"$7.12302","currency":"USD"},{"qty":1000,"price":"$6.20392","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5e181e5abb88c7d00519637b4cbe875d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the equivalent parts for LTC4012IUF#PBF?","answer":"The LTC4012IUF-2#PBF is a pin-compatible alternative with the same package, cell count, and temperature range, but its supply maximum is 16.8V instead of 28V.
