LM3658SDX-A/NOPB

Battery Chargers Overview

The LM3658SDX-A/NOPB is a dual-source USB/AC Li-Ion charger IC from Texas Instruments, designed for single-cell lithium-ion and lithium-polymer batteries. It operates within a supply voltage range of 4.35 V to 6 V and supports an output current of 0 A to 1 A. The device provides a fixed output voltage of 4.2 V and is housed in a WSON-10 package. It functions across an industrial temperature range from -40°C to +85°C.

Battery Chargers Feature Summary

• Supports charging from both USB and AC power sources with automatic source selection.

Battery Chargers Applications

• Portable electronic devices requiring single-cell battery management

Battery Chargers Procurement Notes

Verify the specific suffix 'A' against official documentation to confirm any distinct electrical or mechanical variations compared to standard variants. Ensure compatibility with system input voltage limits and thermal requirements before integration. Cross-reference datasheet specifications for accurate design parameters.

Battery Chargers Selection Notes

Select this component for applications requiring integrated dual-source charging logic in a compact form factor. Evaluate the WSON-10 package constraints against PCB layout capabilities. Confirm that the 1 A maximum charge current aligns with the target battery capacity and thermal dissipation strategy.

Battery Chargers Part Context

This part belongs to the LM3658 series of battery chargers manufactured by Texas Instruments. The series focuses on portable power management solutions. The 'NOPB' designation indicates lead-free and RoHS compliance. The 'SDX' suffix typically denotes the specific tape-and-reel packaging configuration.
