Active production — what it means for your BOM line
The LTC1734LES6-4.2#TRM: This is a multi-chemistry battery charger IC in the LTC1734 family, designed for single-cell Li-Ion, Li-Polymer, or NiMH applications — the chemistry flexibility means the same BOM position can serve different battery types without a board spin.
Supply voltage and thermal envelope
The maximum supply voltage is 8V, which covers the full charge range for a single 4.2V Li-Ion cell plus headroom for the linear regulator dropout — a 5V USB rail or a 5.5V wall adapter both fit comfortably.
Housed in a TSOT-23-6 (SOT-23-6 Thin) package with surface-mount termination — the 0.95 mm pin pitch and 2.9 mm body length fit the standard small-outline footprint used across the LTC1734 family. Supplied on Cut Tape (CT) for prototyping or small-batch production; the same die is also available on tape-and-reel as the LTC1734ES6-4.2#TRMPBF variant.
Compliance and sourcing posture
ROHS3 Compliant per the manufacturer's declaration, so it passes the material-restriction check for EU and UKCA markets without an exemption claim. Sourced to order against your BOM quantity — current pricing and availability confirmed at RFQ time through independent distribution channels.
