No end-of-life notice or last-time-buy window is in effect, so this part is safe to qualify into a new design without a near-term obsolescence risk. The Tape & Reel variant (the #TRPBF suffix) is the standard production reel; Cut Tape quantities are also available for prototyping or small-run builds. ## Programmable timer — set it right for your pack Charge termination relies on an external timer resistor, not on end-of-charge current detection. The designer must calculate the timer period based on the battery capacity and charge current — a mismatch can either terminate prematurely or overcharge. The datasheet gives the formula; verify it against your pack's data before committing the board.","metaTitle":"LTC4006EGN-2#TRPBF Li-Ion Battery Charger IC, 3-Cell 12.6V","metaDescription":"LTC4006EGN-2#TRPBF is an active Li-Ion battery charger IC for 3-cell packs at 12.6V. 28V max supply, -40°C to 85°C, SSOP-16.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","Number of Cells":"3","lifecycle_stage":"eol_hot","Battery Chemistry":"Lithium Ion","Current - Charging":"Constant - Programmable","Battery Pack Voltage":"12.6V","Operating Temperature":"-40°C ~ 85°C (TA)","Programmable Features":"Timer","Voltage - Supply (Max)":"28V","Supplier Device Package":"16-SSOP"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.36","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.36000","currency":"USD"},{"qty":10,"price":"$9.35900","currency":"USD"},{"qty":25,"price":"$8.92400","currency":"USD"},{"qty":100,"price":"$7.74850","currency":"USD"},{"qty":250,"price":"$7.40028","currency":"USD"},{"qty":500,"price":"$6.74730","currency":"USD"},{"qty":1000,"price":"$5.87668","currency":"USD"},{"qty":2500,"price":"$5.65903","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7be85caadf908ed8660ace63db6ac73e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent for LTC4006EGN-2#TRPBF?","answer":"For a 3-cell Li-Ion charger, the LTC4007EGN#TRPBF is the closest functional sibling — it supports 3 to 4 cells and terminates at 16.8V instead of 12.6V. The LTC4002ES8-8.4#TRPBF covers 2-cell (8.4V) applications. Neither is a direct pin-compatible substitute; verify the pinout and external component values before swapping."},{"question":"Can LTC4006EGN-2#TRPBF charge 4 lithium-ion cells?","answer":"No. The part is fixed for a 3-cell series stack with a 12.6V float voltage. A 4-cell pack requires 16.8V, which this charger cannot deliver. Use the LTC4007EGN#TRPBF instead."},{"question":"How to program charge current on LTC4006?","answer":"Charge current is constant and programmable via an external sense resistor and the PROG pin. The datasheet provides the resistor value formula for the desired current. The timer termination is set separately with a resistor on the TIMER pin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LTC4006EGN-2TRPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LTC4006EGN-2TRPBF when reusing this data.
