MC3651RF3AAM

Overview

The MC3651RF3AAM is a battery protection integrated circuit manufactured by Mitsumi Electric Company Ltd. It is designed for single-cell lithium-ion and lithium-polymer battery applications. The device integrates protection functions with an internal field-effect transistor (FET) to ensure safe operation. It belongs to the MC3651 series of power management ICs, providing essential safeguards against overcharge, overdischarge, and short circuits in portable electronic devices.

Feature Summary

• Integrates battery protection logic with an internal FET for compact design
• Supports single-cell lithium-ion and lithium-polymer chemistries
• Provides comprehensive protection against electrical faults

Applications

• Single-cell lithium-ion battery packs
• Lithium-polymer battery protection modules
• Portable consumer electronics requiring integrated protection

Procurement Notes

Verify the exact datasheet version from Mitsumi Electric Company Ltd before procurement. Confirm that the PLP-4E package matches your PCB layout requirements. Ensure compatibility with single-cell Li-ion or Li-Po systems. Check for RoHS compliance status as indicated in official documentation. Validate pinout configurations against your specific application design.

Selection Notes

Select this component when a compact solution integrating both protection logic and switching capability is required. It is suitable for designs where board space is limited due to the inclusion of the internal FET. Consider its suitability for single-cell architectures only. Evaluate thermal performance based on the exposed pad package type. Ensure the application does not require external FET control.

Part Context

This part is part of the MC3651 family of battery management ICs from Mitsumi. Variants such as MC3651DF1AAM share similar functional descriptions but may differ in package or specific electrical characteristics. The MC3651 series focuses on protecting single-cell batteries in portable devices. Always refer to the specific datasheet for the RF3AAM suffix to distinguish it from other family members.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify cross-references through official manufacturer channels or authorized distributors. Do not assume direct pin-to-pin compatibility with other models without explicit datasheet confirmation.
