LM3622MX-8.2

Battery Chargers Overview

The LM3622MX-8.2 is a lithium-ion battery charger controller manufactured by Texas Instruments, designed for single-cell battery management applications. It operates within an input supply voltage range of up to 24V and supports a maximum output charging voltage of 8.2V. The device delivers a constant charging current of 25mA. It is housed in an 8-SOIC surface-mount package with a width of 3.90mm. The component functions reliably across an ambient operating temperature range of -20°C to 70°C.

Battery Chargers Feature Summary

• Integrated control logic for managing the charging cycle of lithium-ion cells
• Supports high input supply voltages up to 24V for flexible power design
• Provides regulated constant current charging capability

Battery Chargers Applications

• Single-cell lithium-ion battery pack management systems
• Portable electronic devices requiring low-current charging solutions
• Battery backup units for consumer electronics

Battery Chargers Procurement Notes

Verify the specific suffix designation when sourcing replacements, as it indicates the fixed output voltage setting. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans. Ensure thermal management aligns with the specified operating temperature range.

Battery Chargers Selection Notes

Select this component when a dedicated controller is required for single-cell Li-ion batteries rather than a complete charge pump solution. Consider the 25mA current limit suitability for small capacity cells. Evaluate the 8-SOIC package constraints against available board space. Verify compatibility with the system's input voltage rails, which can extend up to 24V.

Battery Chargers Part Context

This part belongs to the LM3622 series of battery charger controllers from Texas Instruments. It shares functional similarities with other members of the family but is distinguished by its specific voltage configuration and packaging. The series targets simple, cost-effective charging architectures for portable applications where discrete components are minimized.

Battery Chargers Replacement Considerations

The LM3622MX-8.2/NOPB is a verified equivalent variant offering lead-free compliance. Cross-reference pinouts and electrical specifications carefully when substituting with other single-cell Li-ion controllers from different manufacturers.
