LM3658SD-B/NOPB

Battery Chargers Overview

The LM3658SD-B/NOPB is a single-cell lithium-ion and lithium-polymer battery charger IC manufactured by Texas Instruments. It operates within a supply voltage range of 4.35 V to 6 V and provides a regulated output voltage of 4.2 V. The device supports a programmable charging current up to 1 A. It is housed in a 10-WSON (3x3 mm) package with a bare pad for thermal dissipation. The component functions across an industrial temperature range from -40°C to +85°C.

Battery Chargers Feature Summary

• Integrated dual-source input management supporting both USB and AC power adapters
• Programmable constant-current charging control for single-cell lithium chemistry batteries
• Built-in thermal regulation and overcurrent protection mechanisms

Battery Chargers Applications

• Portable electronic devices requiring single-cell battery charging
• USB-powered consumer electronics
• Battery management systems for mobile gadgets

Battery Chargers Procurement Notes

Verify the specific suffix designation when sourcing, as the LM3658SD-B variant may be obsolete or discontinued depending on the manufacturer's current production status. Confirm RoHS compliance and lead times directly with authorized distributors. Ensure the procurement channel provides valid traceability documentation for quality assurance purposes before finalizing any acquisition.

Battery Chargers Selection Notes

Select this component for applications requiring integrated dual-source input handling without external multiplexing circuitry. It is suitable for designs needing precise thermal management and programmable current limits within a compact WSON footprint. Consider the 4.2 V fixed output configuration for standard single-cell lithium-ion or polymer battery chemistries.

Battery Chargers Part Context

This part belongs to the LM3658 family of battery chargers from Texas Instruments. It serves as a specialized power management solution for portable devices, integrating charge control and source detection into a single small-form-factor package. The device simplifies system design by managing input selection and charging profiles autonomously.
