LM3658SDX/NOPB

Battery Chargers Overview

The LM3658SDX/NOPB is a dual-source USB/AC Li-ion chemistry battery charger manufactured by Texas Instruments. It supports single-cell lithium-ion and lithium-polymer batteries with a fixed output voltage of 4.2 V. The device accepts an input supply voltage ranging from 4.35 V to 6 V and provides a programmable charging current between 0 A and 1 A. It is housed in a WSON-10 package (3x3 mm) designed for surface-mount installation. The component operates within a temperature range of -40°C to +85°C.

Battery Chargers Feature Summary

• Dual source capability supporting both USB and AC power inputs
• Integrated charge management for single-cell lithium-ion and polymer batteries
• Programmable constant-current charging control

Battery Chargers Applications

• Portable electronic devices requiring single-cell battery charging
• USB-powered consumer electronics

Battery Chargers Procurement Notes

Verify the specific suffix and manufacturer details against official datasheets to ensure compatibility with design requirements. Confirm that the WSON-10 package dimensions and thermal characteristics meet the target application's constraints. Cross-reference the part number with the manufacturer's current product status to avoid obsolete components.

Battery Chargers Selection Notes

Select this component when a compact, dual-input solution is required for single-cell lithium-based batteries. Ensure the system design accommodates the 4.35 V to 6 V input range and the 1 A maximum current capability. Verify that the WSON-10 footprint aligns with the PCB layout and that the operating temperature range suits the environmental conditions.

Battery Chargers Part Context

This part belongs to the LM3658 series of battery chargers from Texas Instruments. It is a successor or variant to earlier versions like the LM3658SD-B, which has been discontinued. The NOPB suffix indicates compliance with RoHS standards and absence of lead/bromine. It falls under the PMIC - Power Management ICs category, specifically for charge management applications.

Battery Chargers Replacement Considerations

The LM3658SD-B/NOPB is listed as a direct substitute for the discontinued LM3658SD-B. Verify pinout and electrical specifications match before substitution.
