LP3918TLX is listed in the Battery Chargers range at ChipApex. The manufacturer field lists National Semiconductor. Its product description is POWER SUPPLY SUPPORT CIRCUIT, AD. Review the specifications below when checking this part for your BOM.
The LP3918TLX is a fully integrated battery charge management and regulator unit designed for lithium-ion battery applications. It combines a constant-current/constant-voltage charger with multiple low-dropout regulators in a single package. The device supports I2C-compatible interface control for the LDO regulators, enabling flexible power distribution. It features a compact 25-DSBGA (2.46x2.46 mm) package suitable for space-constrained portable electronics.
Verify the manufacturer origin, as National Semiconductor assets are now part of Texas Instruments. Confirm the specific suffix (e.g., NOPB) indicates lead-free/RoHS compliance if required by your assembly process. Ensure the package type matches your PCB footprint requirements before ordering.
Select this component when a combined charging solution and regulated power rails are needed from a single IC. It is suitable for designs requiring I2C control over output voltages. Consider the thermal performance of the small DSBGA package under maximum load conditions during system design.
This part belongs to the LP3918 family of battery charge management units. It represents a consolidated solution replacing discrete charger and regulator components. The transition from National Semiconductor to Texas Instruments affects documentation sources but not the core functionality or pinout compatibility within the series.
Check for LP3918 variants with different suffixes such as NOPB for environmental compliance. Verify if alternative packages like TLX-A are available if lead times differ. Cross-reference with TI's current portfolio for updated datasheets and recommended replacements.
