Product details

Battery charge management — what this IC does

The Texas Instruments LP3918TL-A/NOPB is a battery charge management IC, purpose-built for charging and managing lithium-based cells. It handles the charge algorithm, termination, and monitoring functions that a discrete charger circuit would need multiple parts to replicate. This is the IC you spec when the BOM calls for a dedicated charge controller rather than a general-purpose PMIC.

No last-time-buy window or NRND flag to track.

Packaging note for the BOM

That matters for the pick-and-place line: if your assembler expects a reel, they'll need a tube or tray adapter, or you'll hand-place for prototype runs. Bulk is common for low-volume or repair-stock orders, but verify your CM's feeder setup before committing the line.

Frequently asked questions

What is the LP3918TL-A/NOPB equivalent?

No direct pin-compatible equivalent is listed in the available records. The BQ2084DBT-V143 is a battery monitor IC from the same functional family but differs in interface (SMBus vs the LP3918's charge management role) and cell count support (2 to 4 cells). Verify your design's charge control requirements before substituting.

Is LP3918TL-A/NOPB compatible with lithium batteries?

Yes — the LP3918 is a battery charge management IC, and its description indicates it is designed for charging lithium-based chemistries. The peer BQ2084DBT-V143 also targets Lithium Ion/Polymer, confirming the family's application space.
