Product details

What this Li-Ion charger IC does and where it fits

The LT3650IMSE-4.2#PBF is a constant-current, constant-voltage (CC/CV) charger IC for single-cell Lithium-Ion or Lithium-Polymer battery packs, with a fixed 4.2V termination voltage. It delivers up to 2A of programmable charge current from a supply rail as high as 32V. The IC includes over-temperature fault protection and a programmable timer for charge termination, making it suitable for portable devices, handheld instruments, and battery-backed systems where a dedicated charging controller is needed.

Package, mounting, and board-fit considerations

Housed in a 12-lead TSSOP package with an exposed pad (12-MSOP-EP), the LT3650IMSE-4.2#PBF is surface-mount only. The part ships in tubes, not tape-and-reel, so plan for manual or tube-fed pick-and-place handling.
