Battery Chargers Procurement Notes

Verify the exact datasheet version from Texas Instruments to confirm pinout compatibility and thermal specifications. Ensure the 8-SOIC package footprint matches your PCB design. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the suffix NOPB with official TI documentation to ensure lead-free material composition.

Battery Chargers Selection Notes

Select this component when designing for single-cell Li-Ion batteries requiring a 4.1V charge termination voltage. Consider the 24V maximum supply voltage capability for systems with varying input sources. Evaluate the 8-SOIC package size against available board space constraints. Verify that the thermal performance meets the requirements of the intended enclosure environment.

Battery Chargers Part Context

This part belongs to the LM3622 series of battery chargers from Texas Instruments. It is specifically tailored for single-cell applications, distinguishing it from multi-cell variants like the LM3622M-8.2/NOPB. The series provides integrated solutions for managing charge cycles in portable devices, ensuring safety and efficiency through built-in control logic.

Battery Chargers Replacement Considerations

Check for LM3622M-8.2/NOPB if dual-cell support is needed, noting the voltage difference. Verify pin-to-pin compatibility with other single-cell Li-Ion chargers from Texas Instruments or third-party manufacturers before substitution.
